When fall arrives and cold air moves in again, all the energy stored in the water gets released into the atmosphere, which, in turn, causes the air above the water to warm up more than usual.

Extratropical cyclones have three stages of expansion: the developing stage, in which an undulating wave develops along the front; the mature stage, in which sinking cold air sweeps equatorward west of the surface low - pressure centre and ascending warm air moves poleward east of the cyclone; and the occluded stage, in which the warm air is entrained within and moved above the polar air and becomes separated from the source region of the tropical air.

Some of the key principles of Eco-Driving are: • Maintain engine speeds between 1200 — 3000 rotations per minute (RPM); • Change to higher gears between 2000 — 2500 RPM, and drive in top gears at lower speeds — the so - called «50 in 4th gear» driving style; • Try to anticipate more to avoid strong accelerations, decelerations, overtaking or aggressive driving; • Driving at speed limits and avoiding high speeds; • Add 10 % to standard tyre pressure; • Avoid using the air condition, or set at temperatures above 21Â °C; • Use your bike for short trips — starting your car when it is «cold» uses 300 % more fuel.»

Although I've seen it in energy budgets I don't think climate models adequately account for latent heat of vaporization which can rapidly and effectively suck heat from the surface making it colder while not heating the air immediately above the surface one tiny bit because the sensible heat of the surface is converted to latent heat of vaporization.
