Decreasing Cyclone frequency in the 21st century.

In our text book at the end of chapter 10, the writers state that as global temperature rises, Rocky Mountain cyclones will occur with less frequency leading to inconsistent precipitation patterns. It is said in our book that the less frequently the cyclones happen, and the slower they become, they will bring more sustained precipitation over a period of time. Think of this past summer's rain patterns. There have been periods of drought, followed by intense rain, and flooding. This is something to watch as we push further into the 21st century.
