Sounds more like a student pilot learning to fly than a storm.TexasF6 wrote:wxman57 wrote:I'm finally back in Houston. Only took 27 hours to travel from Chicago to Houston. Did I miss anything over the last few days?
You missed a stall, wobble, another wobble and the like! Glad you made it in safely.

Is this something like the Weather Channel naming snow storms
spiral wrote:The term' brown ocean' its new to me thinking its likely a media term. When tropical lows or remnant tropical cyclones ramp up over land. he term applied to it then is landphoon. Basically low latitude desert soils (mainly sands) absorb a lot of heat. As outer rain bands of the systems drop water down onto the soil the heat transfers into the water which evaporates and passes rapidly to the surface. This then creates similar convection to what happens over warm sea waters. There have been studies done on this phenomenon. It doesn't necessarily have to be desert, just sufficiently high temperatures for heat to seep into the ground and then sufficient water to create the convection.

Erin is an example of a newly defined type of inland tropical cyclone that maintains or increases strength after landfall, according to NASA-funded research by Theresa Andersen and J. Marshall Shepherd of the University of Georgia in Athens.
Before making landfall, tropical storms gather power from the warm waters of the ocean. Storms in the newly defined category derive their energy instead from the evaporation of abundant soil moisture – a phenomenon that Andersen and Shepherd call the "brown ocean."
"The land essentially mimics the moisture-rich environment of the ocean, where the storm originated," Andersen said.
