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

Weather forecasting is an exercise 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 year, although at the beginning these they did not succeed.

It was only with the advent of new technologies (such as computers) that mathematical models began to be implemented that allowed more accurate predictions to be made, 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.

Here is the weather report for the next few hours in Washington DC:

During this time, wind gusts will reach 44 kilometers per hour during the day and 19 kilometers per hour at night.

Washington DC is the capital of the United States, located in the northeast of the North American country, along the Potomac River, surrounded by the states of Maryland and Virginia.

The climate of this American city is mainly tropical, with the monsoon subtypewhich means that it records high temperatures all year round, with a short dry season and a mainly rainy season.

The highest temperatures they are recorded in July, when it is around 40 degrees; on the other hand, it is in January and February that freezing weather reigns to the point of reaching zero degrees.

Occupying a large swath of territory, the United States reports 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 important time is humid continental which is characterized by constant rains throughout the year which become storms during the summer and snow throughout the winter.

In the southeastern United States the prevailing weather conditions are subtropical wetland 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.
