Weather forecasts, based on observation and mathematical modelshelp predict the state of the atmosphere at a given time and place from records such as temperature, humidity, pressure, precipitation or wind.

Weather forecasting is an activity that has been carried out for hundreds of years, even before the Christian era, based essentially on the observation of the configuration of the clouds, the wind, the time of the year, although initially these they were inaccurate.

It was only with the advent of new technologies (such as computers) that mathematical models began to be implemented, which made it possible to make more accurate predictions, becoming a fundamental factor for the transport (land, sea or air), agriculture, tourism, disaster prevention, public health and even military operationsbeyond deciding whether or not to carry an umbrella or whatever outfit become.

Occupying a large swath of territory, the United States records a wide variety of climates, almost all of them.

East of the United States Two major climates predominate: the humid subtropical and the humid continental.

In the American Northeast the most dominant climate is the humid continental which is characterized by constant rains throughout the year which turn into storms in the summer and snow throughout the winter.

In the southeastern United States the prevailing weather conditions are humid subtropical it has hot summers, cool winters and abundant rainfall.

American West Sidethere are at least three major predominant climates: semi-arid, arid and Mediterranean.

The semi-arid climate, in its cold subtypeencompasses the westernmost and north-southmost part of the United Statescharacterized by low rainfall and low temperatures.

In the southwestern United States this is where he is arid climate, both in its cold and hot subtypes. In the cold and arid regions, the winters are freezing and the summers mild, while in the hot and arid regions, the summer records extremely high temperatures and in the winter the weather is mild. In both cases, precipitation is rare.

The Mediterranean climate enroll yourself in the most coastal area of ​​the American West, from north to south and is characterized by its mild and rainy winters, as well as its dry and hot summers.
