A brief discussion of the environment is given at the end. Details of the models can be found at the links in the preceding paragraphs. They show several distinct layers. This over-water fetch has probably led its formation at the base of the otherwise hot and dry air leaving the continent. RH increases with height in the 12Z sounding.
Winds are westerly.
It shows the same layered structure seen in the radiosonde soundings. Some small differences include a drier MBL and a shallower elevated mixed layer. In this image WSW is on the left, and ENE is to the right. This image shows a tongue of moderate extinction due to sulfate aerosol in the elevated mixed layer. Low amounts of sulfate aerosol are found in the free troposphere.
