When we plan to visit a different country, we usually look at the weather forecast so that we can pack our bags accordingly. The weather forecast is also used to get an indication of any natural disasters like a cyclone. The meteorologists predict the weather in many ways. Here are some of the ways it is done.
This method works best in places where the weather remains more or less same in particular days of the year. That is, for places that have similar weather patterns most of the time you can predict the weather using this method easily. Thermometers and barometers are used to predict the weather.
Historical data of a number of years are studied to predict the weather. The meteorologists use previous data to forecast future temperature changes. They will look at the data of previous years at the same time of the year if conditions remain normal to predict the weather.
This is a modern method of forecasting the weather. Mathematical formulas are used to predict the weather. The meteorologists need to enter the present data into the formula and get data for future weather conditions. This method of predicting the weather can get very accurate results.
Predicting the weather is important to save people from natural disasters. It gives people the chance to prepare for any upcoming cyclone or storm. The activities of the airline industry, shipping industry, and others depend a lot on the weather. So, they must look at the weather forecast every day.
