How does weather forecasting work?

The only recurring occurrence on Earth is the constant change in Weather. With so much technology at our disposal we still struggle with weather predictions. The art of accurate weather prediction rests within the controlling factor of the weather. We haven't been able to get a very direct answer but weather stations look for certain key geographical indicators that help them give you an estimation of the weather.

1. The Oceans

This one is perhaps the biggest indicator available on Earth and I mean this literally. The heating and cooling of Oceans can tell us the direction of winds. We can also get to know the temperature that the coast can experience from the oceans. If you have gone through School, you must have read about the land breeze and Sea breeze phenomenon. Since winds move from colder to warmer areas, we can get to know if the land is cooler than the water or vice versa. As we can estimate the positioning of the Sun before hand, we can estimate the temperatures based on how hot or cold an Ocean will be.

2. Satellites

This one is perhaps the most accurate till date as it gives us a birds eye view of the weather changes as it is happening. This might make you think that this should be pretty accurate as you can literally see whats happening with the weather. But you cannot be more wrong. Since the Earth is constantly moving, the heating effect of the sun also changes. This causes sudden changes which is why weather forecasts tend to be so unpredictable. Satellites though have been life savers as they can easily predict storms long before they hit.

3. The winds

Wind speed measurement is the most popular technique used by weather forecasters. It tells weather stations about incoming clouds and the direction that they are moving in. Stormy weather can be predicted from winds much before hand. Blowing of winds are an indicator of pressure differences on Earth.

Off the top of my mind these are the most popular techniques used for weather prediction. Accuracy can only be increased if we can predict the positioning of the sun and Earth and also be able to predict the amount of heat that the Earth will receive at that moment. Since this is very difficult to do at such a large scale, we haven't been able to do this.

As always....
