One of the main branches of meteorology is one that deals with predicting the weather to be in a certain place in the coming hours, days, weeks, months or years.

It is based on the measurement of certain parameters such as humidity and atmospheric pressure. It takes into account phenomena such as the mass of clouds that are observed in the images captured by satellites.

Scientific forecast

There have been many advances in the scientific study of weather forecasting. One of the main advances is related to communications, since the incorporation of technological means such as fax has allowed information reached many meteorological services at the same time.

The analysis requires several meteorological measurements of parameters such as wind and temperature on the Earth's surface and the upper atmosphere from different places. Hence the importance of the data are transferred from some other think tanks.

In meteorological measurements are made now will automatically through sophisticated means and thousands of weather stations spread over the planet.

Moreover, the images captured by satellites are received in all weather centers having the receiving devices required.

Once obtained data, the study meteorologists to predict their behavior according to their knowledge and experience of what usually happens, because there are many variables that influence the climate.

Prediction popular

The first day will tell us the time August, the second day of September, and so on. From the day 13 interpretations differ, but some used these days to know the wind and fog of each month.

Remarks

Many other predictions are based on the observation of the animals, such as the presence of many insects flying ants can be seen as a sign of rain.
