Ask The Weatherman for August 30, 2013:

Question: What is a warm core weather system?

Answer: A warm core weather system is just that. It means that from the surface to the upper levels, the air inside the storm is warm and very humid. The best weather features that we have on the weather map that represent this are the Bermuda-Azores high pressure in the Atlantic Ocean, the Pacific High pressure in the Pacific Ocean, and of course tropical weather systems.
