A Portable Wind Or Weather Meter is an Essential Tool For Soldiers and Military Personnel

Why would a soldier need a portable handheld wind or weather meter? There are many reasons that a handheld weather meter is an essential and potentially life-saving tool for actively deployed military personnel or military personnel in training.

Crosswind can be the worst enemy of a military sniper or sharpshooter. Crosswind has a very strong influence on the accuracy of a sharpshooter, even a light to medium crosswind can cause deviations in the bullet's trajectory. Other weather conditions play an important part as well. Temperature, humidity and density altitude all must be taken into account when sharpshooting. This is where a portable weather meter really shines. A full featured weather meter can provide the readings necessary for a soldier to compensate for the current environmental conditions. It can make all the difference between a missed shot and hitting the target.

Soldiers are certainly no stranger to extreme weather conditions. Portable weather meters can give soldiers the environmental measurements they need in order to make accurate decisions as to work periods, rest periods and hydration. This is vital whether they are in a training exercise or in combat. Having instant and accurate weather and environmental information can mean the difference between life and death.

A military drop zone is not the place to play guessing games about the current wind conditions. To get the job done right and safely a portable wind meter is essential gear for parachutists and military personnel in the drop zone area. Failing to know the wind conditions and properly compensating for them can mean a failed operation.

These are just a few good reasons that every soldier should have a pocket wind or weather meter in their arsenal. It can make all the difference in them getting back home to their families safely!

Winter Weather in Peru

For people with only a rough geographical knowledge of Peru, intuitive knowledge should dictate a couple of things about the seasons in Peru. First, like other countries in the southern hemisphere, the seasons are reversed from those in the northern hemisphere; the high summer months are December, January, and February, whereas the key winter months are June through August. Second, the country is fairly close to the equator and should have a year round warm tropical climate.

Well, you can toss both those assumptions out the window. This is because Peru's geography gives it some unique climatic features. The Andes mountain range, which runs through the middle of the country is the principal reason for this. A second factor is the cold water Humboldt Current, also known as the Peru Current, which runs up the coast of Chile to southern Peru. As a consequence of these attributes, the coast, the mountains, and the jungle each have distinct winter climates.

Coast

In general, the Peruvian coastal climate is characterized by moderate temperatures, little rainfall, and high humidity. The abovementioned Humboldt Current results in semi-arid conditions all along the coast. The northern coast, closer to the equator, is generally warmer and wetter. In the winter month of June, July, and August, visitors can expect clouds, cool temperatures, and some humidity. The northern coast tends to be warm and comfortable with little rain. Meanwhile, on the central and south coasts, travelers can expect overcast skies. One winter phenomenon unique to Peru, as well as parts of Chile, is the garua, a term for the permanent layer of fog that covers the coast in the winter.

Mountains

Known in Spanish as the sierra, the mountains or highlands in Peru have a very distinct climate. In this region, winter does not exist as such; instead, there is a dry season and a rainy season. In addition, temperatures and humidity remain fairly low year round because of the high elevation. The dry season - June, July, and August - brings cold mornings and nights and almost no rain. The rainy season, mainly January and February, are typified by high precipitation. Also, if it rains, the cloud cover helps to maintain higher temperatures, although these never go above 70 degrees Fahrenheit. However, even during the dry season, there is a change of snowfall at higher elevations - above 3,800 meters.

Jungle

The jungle presents yet another variation in weather, determined mainly by the equatorial climate of the Amazon rainforest. Visitors to the jungle can expect a lot of rainfall and generally high temperatures all year round. The exception in the southern jungle, where there is a chance of colder temperatures from May until August. These cold surges come from further south and generally last only a few days. As in the mountain region, the months between June and August are somewhat of a dry season.

Guatemala Fishing Season and Weather

Eternal spring - as Guatemala is known as - refers to the temperate climate that the highlands enjoy and exploit for cultivation. Its two cash crops of coffee and flowers thrive in this consistent environment.

This familiarity persists today, although it can be misleading. While in Guatemala you can experience comfortable spring breezes, hot and humid tropical weather and very cold nights (below 0°C ), all in the same day, depending on where in Guatemala you are.

The average annual temperature in the highlands above 3,000 meters (9840 ft) is 15°C (59°F), while in the lowlands the average is 25°C (77°F). In the lowlands and towards the Pacific Coast that preoccupies most fishermen, the temperature can reach 38°C (89°F) or greater - with peak temperature and humidity mid-year.

The term itself "Land of Eternal Spring" was first used to give the image of a country and countryside that was in perpetual bloom. Away from the coast, the land rises towards the volcanoes and the climate becomes temperate and ideal for cultivation - hence blossoming month to month. Flower cultivation and export (primarily roses) continues to be a major industry in Guatemala today - in fact one of the largest rose farms in the world can be found just outside the ancient capital of Antigua.

The tag though is is a bit misleading - as there are effectively only two seasons: the dry season and the rainy season. The longer season is the rainy season, which lasts from May through October (often with a pleasant intermission in August) followed by the dry season which lasts from January through April.

Guatemala boasts some of the world's most consistently flat seas - often as far out as 50 miles it can be calm and almost like a lake. Observing the geography of the coastline, you can see how the waters form a large protected bowl with Mexico at the top and Panama at the bottom.

This combined with the protection offered from the prevailing winds by the highlands and the ridge of volcanoes means that the coast and coastal waters are almost wind free on a year round basis, with late February through May almost guaranteeing flat seas.

During the dry season - and the height of the sailfishing season of November - May, it is highly unusual to see any problems with weather impacting the sportfishing fleet's ability to leave the dock. Even during the wet season, the weather offshore can vary significantly to the coastal weather - but there is certainly a greater propensity for weather delays or to be "blown out" in the Summer months.

Remember however that just when the wind is providing some cooling effects while fishing - it remains mandatory however to prudently apply high factor sun protection..........this is a must when fishing offshore all year round in Guatemala, along with high quality sunglasses and a wide brimmed hat for screening your head.

The Greatsailfishing Company owns and operates its own fleet of Bertram sportfishing boats and private villas for fishing trips in Guatemala. We have just completed our 8th successful season in The Sailfish Capital of the World.For more information on this remarkable fishery - and to receive a FREE eBook with 16 information filled chapters about fishing and travelling in Guatemala click here - http://www.greatsailfishing.com/

Jamaica Weather - Understanding the Importance to the Island

Jamaica weather, like the other islands of Caribbean, has a tropical marine climate. It is called marine because of the influence of the sea. During the day the sea is usually cooler than the land. Winds blowing from the sea to the land will help cool the land. At night the land loses heat rapidly and cools down.

In Jamaica, the night is generally cooler than the day. The sea moderates the temperature that makes it neither too hot nor too cold at any time of the year. The land has warm temperatures throughout the year.

The climatic condition on the island has no marked change in the temperature from one season to another. Other things that influence the climate of Jamaica are the sea, the relief of the land and winds. Places close to the coast will feel the effect of the sea breeze on the land during the days.

The country is very hilly and mountainous and the hills extend from east to west across the island. If you live on the plains and take a trip into the hills, you should notice that it becomes cooler as you go higher. The reason for this is that for every increase of about 100 meters in height of land, the temperature falls to 1 degree Celsius. Towns such as Mandeville, Christiana, Moneague and Malvern have cooler temperatures during the year than places on the plain such as Ocho Rios and St. Ann's Bay. You can find these places easily on your map.

The weather is modified by the sea and by the mountainous nature of the country. The eastern portion of the island is crossed by the Blue Mountain range, rising from 900m to 2,256m; the central and western portions consist of interior mountain ranges surrounded by high Limestone plateau 305m to 900m and the south side of extensive plains less than 132m high.

There is considerable variation in the climate of the different regions. The coastal plains are hottest and driest, the climate of the limestone plateau sub-tropical and the higher areas much cooler.

The weather contributes to a climate that is comfortable and promotes a healthy environment. Because of the year round effect of sea breezes, there is little variation between summer and winter temperatures, the coolest months being December to March. However, there is a variation in day and night temperatures and greater variation between temperatures at high and low altitudes.

August is generally the warmest month of the year and February the coolest. Seasonal differences between these two months are usually less than 10 degrees, being often in the order of five degrees Celsius.

Relative humidity is fairly high although not as much as in places nearer the equator. In Kingston it ranges from 63 per cent in February to 5 per cent in October. Montego Bay is rather more humid, with an annual range between 71 and 77 per cent.

The island experiences its rainiest time occurring in May and June and again in September and October, this is sometimes extended to December. Jamaica has three types of rainfalls, the relief that is caused by moisture laden winds, this happens mostly in the Portland area.

The second type is convectional, where there is heavy rain fall for short periods of time, a lot of afternoon rains and finally, there is frontal, when warm air and cold air meets and this is called a cold front.

In Jamaica the hurricane season starts from June 1 to November 30 and the country is in a hurricane belt so it gets its fair share. However, with the increased in technology and the meteorological services giving warnings in advance, persons can be better prepared. It is always advisable when travelling to check what the weather is like in that location so you don't get caught in a hurricane.

Photography Course Online - Adverse Weather Can Ruin Your Valuable Camera

Cameras need constant care and attention to keep in optimum operational condition. They generally require daily attention if you are traveling and even more in adverse conditions. Here is a guide to help care for your camera when conditions become extreme.

Extreme Cold

Carry your camera equipment in a hermetically sealed metal case; a complete seal is important. Gaffer tape can be used as a sealant against fine snow and is effective down to -10 degrees C. Take great care when touching metal parts especially with the face. Skin sticks to frozen metal and can be torn off to remove; this is extremely painful.

Try to keep your equipment at a constant temperature as much as possible. Relocating into a warm room straight from the cold causes condensation to form. When taken outside again the moisture freezes on contact with sub zero temperatures. Both the moisture and ice in your camera will almost certainly cause problems. A way to avert this is to put your equipment in separate sealed plastic bags with packets of silica gel. Examine your camera design thoroughly by means of a photography course online and learn how to deal with the issues of extreme conditions and the impact on your camera equipment.

Extreme Heat

Ground temperatures in many deserts can exceed 50 degrees C. Cameras and associated equipment left in these temperatures can become untouchable. In addition direct sunlight on a camera may melt the cement and glue holding components in place. Today, many metal parts have been replaced by plastic; these can also melt under these temperatures. Keep equipment in silver colored cases to reflect the sun away from your equipment. Clean and maintain your equipment at night when its cool. A camera wrapped in chamois leather at night will stay cool well into the day.

High Humidity

The tropics give high humidity and this is also a major problem for camera equipment. Moving between air-conditioned buildings and the outside humid, damp air fogs glass and takes a long time to clear. Keep all equipment constantly outside rather than inside is best if possible. In the damp heat fungus grows on many materials used in your camera. Small insects may decide to make your camera home.

After returning from a trip to India my Nikon SLR metering system failed. I subsequently sent it off for repair. The camera was returned with a note saying a family of spiders took up residence. They were alive all this time and feeding off fungus. Sealing your camera in a plastic bag is the best way to prevent this from occurring. Learn about the impact of humidity on camera equipment through a respectable photography course online and take the appropriate precautionary action.

Excessive Dust

This is a huge problem for SLR cameras particularly if you use prime lenses and changing them frequently. Dust gets inside and makes its way to the sensor and stays put. It can be extremely difficult to remove if not impossible. You may have to send the camera away for professional cleaning and this is expensive. Gone are the days when a blower brush would get you out of trouble. Keep your camera in a well sealed bag when exposed to dust. Consult a reputable photography course online to find out the specifics of your cameras controls and design.

Sea Water

Salt water and even sea air can cause permanent damage to your camera equipment. If you are working in a sea side location you need to take precautions. The best protection again sea water damage is good insurance and a water proof housing. If your camera falls unprotected into sea water, the best thing to do is to throw it away and buy a new one. It will be utterly ruined. If you wish to try and salvage the camera, rinse it thoroughly in clean water and take it immediately to a professional repairer. I have been able to salvage mechanical cameras this way, but with electronic it's much more difficult.

By taking the precautions mentioned here you will be able to avert the many problems that adverse conditions present. This is important to you as high quality cameras are expensive and are vulnerable to the elements. Examine your camera design thoroughly by means of a photography course online and learn how to deal with the issues of extreme conditions and the impact on your camera equipment. Reduce these risks and enjoy years of use from your cameras and lenses.

Weather In Bandung

Situated little above 750 meters above sea level and surrounded by many volcanic hills of Parahyangan mountains, Bandung is the capital of west Java province in Indonesia. It has a tropical climate and remains cooler than most other places in Indonesia. The temperature hovers around 25-30o Celsius during the day time and 18-25o Celsius at night around the year. Typical to tropical climate, Bandung does not have distinct winters or summers and temperature remains mostly constant throughout the year with mild fluctuations. In fact, the weather here can be classified into wet and dry since monsoon places such an important role in the climate of the place.

Wet season in Bandung starts from early October and lasts till late April. During the period from November till March Bandung witnesses heavy rainfall with thunderstorms. During these months, Cipularang toll road which connects Jakarta to Bandung often gets disrupted because of landslides which cause huge traffic jams.

During the wet months, humidity is quite high which makes stay very uncomfortable here. Humidity along with tropical diseases like dengue, malaria and flue are very common in part of the world. With an average humidity of 85 percent, temperature touching almost 30o Celsius and average precipitation of 220 millimetres per month, wet season is not the most ideal time to visit Bandung. But being the third largest city of Indonesia, Bandung seldom struggles in gathering tourists at any time of the year. In fact, during the wet season, hotels in Bandung give heavy discounts to attract tourists, and for many travellers especially from within Indonesia and adherent travellers, Bandung can be very much called as a weekend escape.

Months from May to September are considered as the dry season. During this time, rainfall is minimal, humidity goes down substantially, and the weather remains clear and sunny. It is best to visit Bandung during the dry months from June till September. Plenty of sun light lures hordes of tourists from across the globe to visit Bandung at this point of the year.

Though there are the occasional un-seasonal rains, but these do not last very long. The day time temperature is quite high because of the sunlight, but since humidity is less, the weather remains bearable. The weather becomes pleasant during the evenings and nights. The dry months are the best time to visit Bandung and tourists get plenty of warm dry days and cool evenings during these months.

The dry season is obviously the best time to visit Bandung as this is a worry free time and tourists do not have to worry about the heavy rainfall and frequent thunderstorm. Tourists from different parts of the world visit here during this season and getting hotel rooms in Bandung in the dry season is quite difficult due to the huge number of tourists who come here for a holiday.
