arizona 2009 monsoon
Wherever you are in the world is not likely to snow above you. Even in summer, or in the tropics, the ice crystals found in cirrus clouds further temperatures are much below zero. The fact is most precipitation on Earth begins its life as ice crystals in the upper reaches of the atmosphere, and if they fall as rain or snow depends on the temperature of the air that these crystals fall before reaching the ground.
One of the best sites of nature is a landscape snowy thick, cool. Snow is common in winter in northern Europe and North America and is permanent in some mountaintops (and the poles). Mount Kilimanjaro is located just 3 degrees south of Ecuador, but still high enough to maintain a permanent snow cover.
Snowflakes formed when ice crystals adhere to each other. The further development of snowflakes from 0 º C and -5 º C, instead of much colder conditions. In these warmer temperatures the snow may contain more moisture and therefore have large scales. As snow falls on the melting process extracts the latent heat the surrounding air, causing it to cool and refrozen snowflakes. The merger allows refrozen snow crystals that are combined into large flakes.
Snow falling at temperatures below freezing will be fine and powder, ideal conditions for skiing, while snow is formed at temperatures much closer to the freezing tend to be larger, more humid and sticky. In the mountains of snow accumulation causes dangerous avalanches that can sweep all before them in a destructive wave. It is estimated that more than one million avalanches every year, but fortunately most of these rumble away in remote areas where there is little contact with man.
More common in populated areas, but equally dangerous are blizzards. Blizzards are a combination of heavy snowfalls, low temperatures and strong winds. A blizzard can easily lead to a complete standstill city, and the associated Whiteout conditions, when heavy snow and low clouds made it impossible distinguish between heaven and earth, it is extremely difficult to travel even short distances.
In China this past winter (2007-2008) the worst winter storms wrapped in 50 years over large areas of almost 5 months of October from 2007. With power lines pulled down and the traffic infrastructure, sometimes be brought to a complete standstill was over $ 8 million in damages. In northwest China's 1.65 million people were left with either freezing or snow blindness, or both. 500,000 livestock were killed and 3 million die of hunger. 350,000 people were also in need of food and 130,000 had run fuel. In the Beijing-Zhuhai highway had a backlog of 75 kilometers of traffic with over 10,000 abandoned vehicles as soldiers worked to ice of the road.
This explains why blizzard warnings are so important in countries where winter storms are common. A forecast exact can ensure that people at home and not traveling on the Blizzard strikes, reducing deaths and alert the emergency services before the appearance of storms.

Global Monsoon System (Hardcover)
$385.03 This book presents a current review of the science of monsoon research and forecasting. The contents are based on the invited reviews presented at the World Meteorological Organization`s Fourth International Workshop on Monsoons in late 2008, with subsequent manuscripts revised from 2009 to early 2010. The book builds on the concept that the monsoons in various parts of the globe can be viewed as components of an integrated global monsoon system, while emphasizing that significant region-specific characteristics are present in individual monsoon regions. The topics covered include all major monsoon regions and time scales (mesoscale, synoptic, intraseasonal, interannual, decadal, and climate change). It is intended to provide an updated comprehensive review of the current status of knowledge, modeling capability, and future directions in the research of monsoon systems around the world. |
