Today's Lesson on why the North East US has been getting clobbered by
Severe Weather.

This is mostly pictures which explainsthe dynamics of the tropical
circulation which originates along the equator and has
"teleconnections" for events thousands of miles away.

Heavy with graphics, this is 1 megabyte of images, including the major
hurricane in the Pacific, Typhoon Ewiniar, category 3 currently. Solar
heating and nightime cooling creates dynamics which are plainly visible
on satellite imagery. The Inter-Tropical Convergence Zone (ITCZ for
short) is shown from Africa to Asia across the Atlantic and Pacific
Oceans, and the North American offramp of the storm superhighway is
seen through INFRARED VISION. IR radiation, the global warming form, is
visible through several channels used by satellite instruments. We can
see heat, and we can see water vapor too thin to be visible by the
human eye. We can roughly gauge the power of hurricanes from their heat
signatures. The bright purple color of daytime Africa and North America
is plainly visible, and you can tell what time it is by the color of
purple on the land masses. That's heat energy, and it's not invisible
to science. It's not even invisible to the general public who visits
the NOAA satellite access website. http://www.ssd.noaa.gov/
