If you are interested in analysing weather data and making predictions such as rainfall, storm, etc., then Mathematica has nice functionality that you can use. In this article, let me cover a few basic functions in this category.
Let us start by getting the coordinates of the place for which we wish to get the Weather data.
Getting Location Coordinates
Although we can get the weather data using the above coordinates directly, we can also find out the weather stations near the location and use those.
Locating Weather Stations
Here is another way:
Another Way to Get Weather Stations
The last command above returns the 3 “nearest” weather stations close to the coordinates.
Now that we have the coordinates and the weather station names, we can easily get the current weather data.
Current Weather Data
Like the above properties, we can get data for “Visibility”, “Pressure”, “WindSpeed”, etc.
Just as we can get the “current” weather data, there is another interesting function called “WeatherForecastData[]” for forecasting the weather for 1 week starting “today”. The following gives “Temperature” data for the next week.
Forcasting Temperature
Similarly, we can get 1 week’s forecast for “Humidity”:
Forecasting Humidity
Instead of a Table, we can represent as a graph as well:
Plot of Humidity
Finally, if you choose to, you can even render it on a map:
Rendering as Map
Isn’t it nice?
How can we use the Weather data (including forecast) for predicting rainfall, storm, etc? Obviously, we need a good, proven model that is based on the fundamental weather parameters, seasonality, altitude, etc. Such a model can then be implemented in Mathematica and used for prediction.

Have a nice weekend!
