if you want to see where the energy is look in the oceans. Albatross in the comments points to an analysis by the NOAA Environmental Visualization Lab of the engine room for Super Typhoon Haiyan below the surface of the ocean.
Greg Laden goes through this layer by layer from the surface down
The intensification of Super Typhoon Haiyan is being fueled by "ideal" environmental conditions - namely low wind shear and warm ocean temperatures. Maximum sustained winds are currently at 195 mph, well above the Category 5 classification used for Atlantic and East Pacific hurricanes. Plotted here is the average Tropical Cyclone Heat Potential product for October 28 - November 3, 2013, taken directly from NOAA View. This dataset, developed by NOAA/AOML, shows the total amount of heat energy available for the storm to absorb, not just on the surface, but integrated through the water column. Deeper, warmer pools of water are colored purple, though any region colored from pink to purple has sufficient energy to fuel storm intensification. The dotted line represents the best-track and forecast data as of 16:00 UTC on November 7, 2013.
The IPCC has a comment about storm surge, or at least the base upon which the surge was built. The Western Pacific is one of the places where the sea level has been rising fastest.
Jeff Masters, at Weather Underground compiles the rankings and Haiyan comes first at 195 mph at landfall.
