What are the methods employed in weather forecasting?

Modern weather forecasting not only proves highly complex but also greatly quantitative in nature. Thus, in this endeavor, several methods are used, and they include the following.

Synoptic weather forecasting is the traditional technique and was in use until the late ‘50s. In this context, there’s the observation of various weather elements in relation to a specific time and . A synoptic chart is a weather map that depicts atmospheric conditions at a specific time, and several of these were prepared every day to produce an average view of changing weather pattern.

There are numerical methods as well, involving plenty of mathematics. There’s Numerical Weather Prediction (NWP), a method based on the fact that gases present in the atmosphere follow a number of physical principles. When these present conditions are known, the physical laws may help forecast future weather. Mathematical models prove crucial in these techniques.

Alongside numerical weather prediction, statistical methods also help forecast weather, often supplementing the former. They use previous weather data records assuming that the future will be a repetition of such. They are useful for predicting the overall weather, such as in looking at the maximum temperature for a day at a particular location.

Modern technologies are fast enabling meteorologists and researchers to answer more complex questions with a greater degree of accuracy.
