Coastal Water Vapor and the new state of play of tropical depressions.

The Weather Channel Actual High Temperatures

What am I looking for besides the heat index? 

Hurricanes. Yes?  





Brace yourself for the heat and humidity (click here) Published : Monday, 15 Jul 2013, 5:19 AM EDT NEW HAVEN, Conn. (WTNH) -- Anyone who felt miserable in the heat wave earlier in the month won't be a fan of the weather this week. But you'll definitely need a fan, or air conditioning.
"We're going to add some serious heat this week," Storm Team 8 Meteorologist Gil Simmons said. "This is going to be rough."

It's not so much the actual temperature as it is the combination of heat and humidity. The 'Heat Index' was already in the 80s at 5:00 a.m., and was expected to get around 100 later in the day....

The current climate circumstances started a few days ago. It was a sea change in seeking water vapor. The system is slightly similar to the system that spawned Sandy last year. Arctic Origins but dipping below TO the continental - ocean borders.

The margins of the system are consolidating. Now what difference does that make? Well the water vapor in the south is limited. The margins are going to collapse into a tighter circulation system that now has to share it's VELOCITY in a smaller water vapor distribution. Guess what is going to happen when the 'heat calories' become more and more concentrated in their 'geological' water vapor content?

Yep. More turbulence. Turn up the heat with no release into the ocean and we are cookin'. It is really easy to note the difference in Water Vapor along the equatorial margin in these satellites. When the water vapor distribution was wide on July 11th the equatorial water vapor was basically undisturbed. Now it is starved and the current turbulence of the concentrated system has robbed that water vapor to assist in heat concentration. The higher the water vapor concentration in a system the more volatile it becomes.

These are coastal temperatures. If one recalls I frequently mention 'sea spray' as a source of water vapor for the modern day tropical depressions and their acceleration. The Western Gulf is where the current system is consolidating.

That is a full 1.1 degrees above average. As each year has gone by that 'average' increases in minor measure, but, it does increase. The average is a moving baseline and does not reflect the optimal temperatures for a healthy troposphere at all. But, the average is a strong indication past years have been significantly lower.
