TERRE HAUTE, Ind. (WTHI) - When it comes to our forecasting, we take into account something called cyclogenesis.
Simply put, this is the strengthening or development of a low-pressure system that brings us storms.
All storms are a form of a cyclone.
The first is a stationary front.
This can be referred to as the calm before the storm.
Neither the cold or warm front has more of an effect on the other.
The next is called the wave stage.
In this one, the warm and cold fronts become stronger, separating from one another.
Next is the open stage.
This is when we start to get rotation.
Warm air moves up from the south, while cold air pushes in from the west, starting a counterclockwise rotation.
The front after that is called an occluded front.
This is when the cold front starts to take over the warm front.
The majority of storm development happens at this stage.
At this point, most of the cyclones energy has been used and the system will soon die off,
When we look at maps of the surface, we have to pay close attention to the stage a storm is in.
Sometimes storms out west can fall apart before it gets to us, depending on what stage it's in.
