Gulf of Mexico Surface Temperatures and Possible Upwelling

IMAGE SHOULD LOOP FROM Aug.28 - Sept. 07

This Gulf of Mexico image loop runs from August 28 through September 6, 2008.  To make sense of the loop you must observe the dates at the upper right of the image.

We often hear and read that 80° Fahrenheit is a minimum sea surface temperature for tropical systems to develop, and strengthen such that they survive.  That makes this graphic’s temperature scale relatively easy to interpret and make deductions because 26° Celsius is equivalent to 81° Fahrenheit and that is about the boundary between the “hot” colors and the “cool” colors.  Thus, when you watch the loop you will be seeing conditions conducive to the maintenance and possible strengthening of HURRICANE IKE if it travels over Gulf waters.  Forecasts are in great agreement that it will.

You might find the emergence of yellows interesting in the loop.  I’m quite certain that it is related to Gustav winds in that area during those designated days causing surface water to move toward the northwest allowing slightly cooler water to well up from below.  Upwelling is a very important phenomenon in oceans, not only with strong storm winds but also on a larger planetary scale along the western margins of the continents. – If you are interested in upwelling and its importance, please read on
