SST's and T-CHIP
What's the difference? On heat content maps tht show SST's it looks like the seventh circle of hell. On the TCHIP maps it shows a lot of blue along with some red. Which is the most reliable?

By TCHIP, I believe you are referring to TCHP (Tropical Cyclone Heat Potential)?
If so, then a simple answer is both. It is possible to have both high surface temperatures and lower TCHP. Perhaps the water is shallow, and thus may not have as large a supply of heat available to a storm. Or the water may only be very warm through a very shallow depth and cooler underneath.
The motion of the storm is also going to play a part here. TCHP will be more important for a very slow moving storm, as increased residence time over a particular area of water should generally result in the overturning of more water. If it's moving very quickly, then the heat available over a shallower depth may be important, and the SSTs may give a good indicator. It's a situation that could be rather specific to a particular system, so it's good to be aware of how both the surface temperatures as well as the heat content through a deeper column are behaving.
