Starting places of the water causing heavy rain in this land one and a half years ago

In fall one and a half years ago, a low air-push area called Boris brought a lot of rain to this land and caused high water going over places. Understanding where the water came from is important for planning for such things in the coming time. Here we followed water with a computer to find out where it started and how it moved through the air. We saw that a lot of water came from the middle water and from the right big land. The part from the middle water was probably so big because of the warm water top at the time. With the help of a second computer we found that if the top of the middle water had been less warm, there would have been less water from there and also less rain in this land. This means that such rain could happen more often with world warming.
