Rain Forecasting - Meteorology .. Computers work

Rain Forecasting

Rain forecasting is not easy, as it requires very complex mathematical calculations based on measuring the rainfall rate at the intersection points of imaginary perpendicular lines covering the entire country, each line being about forty-five kilometers away from the adjacent line that parallels it. These measurements are entered into the computer supported by other information about the weather conditions, and the computer performs the necessary mathematical analyses to predict daily rainfall.

This method of rain forecasting has only become practical in the past few years, due to the very complex mathematical analyses it requires, which require high-speed and powerful computers that have only recently become available at reasonable prices.

Satellite System

Despite the great progress achieved in the field of meteorology thanks to the computer, accurate forecasting requires a large amount of data from different parts of the globe. For example, accurate tracking of air mass movements requires global information that is not limited to a small part of the globe. In recent years, special satellites have been used to monitor weather conditions such as the movement of air masses and the spread of clouds and send information and photographs about them.

However, predicting weather conditions reliably for a period of a week or more requires a global satellite system capable of directly measuring weather conditions and not just monitoring them, which is expected to be developed in the future.
