<span>The coriolis effect does this. This is a inertial force that acts on objects that are in motion relative to a rotating reference frame. This means that when the earth rotates, objects in the north hemisphere is deflected to the right, while objects in the southern hemisphere are deflected to the left. This makes the winds shift left or right.</span>
There are several reasons that rain predictions made by meteorologists are sometimes incorrect, such as :
- Too many factors that could cause the rain
- Some of those factors could easily change in a short period of time
- We still hasn't developed a 100% solid method to make the prediction
hope this helps
Grids, and variables are used to find a coordinate.
