Dmax: Diurnal Maximum is an intense flare up at convection just before sunrise and DMIN is the opposite. Dmax occurs just before sunrise when the differences in temperatures between the ocean and the air are the greatest; helps to create instability and convection
Dmin: Diurnal Minimum; this occurs just before sunset when the differences in temperatures between the ocean and the air are the least; generally a weakening in convection occurs at this time.
