What happens after a occluded front?

After an occluded front passes temperatures drop if it was a cold front, and rise if it was a warm front. Pressure rises, and there is light-to-moderate precipitation, followed by clearing. Visibility improves and there is a slight drop in the dew-point if it is a cold-occluded front and a slight rise if a warm-occluded front.

Does thermal energy heat rise or drop?

Neither, heat is a form of energy and as such is contained within matter or exists as radiation. Heat energy and hot matter are very different things. In a fluid, hot matter will rise because it expands and hence decreases in density.

Do cold radiation waves go down?

There is no such thing as cold radiation. Cold is nothing in itself; it is merely the absence of heat - or just less heat. Heat, like light, radiates, but cold, like darkness, does not.What you may think of is cold convection; i.e., the fact that cold air will sink and warm air will rise. This effect is often confused as being 'cold radiation'.

Does hot air rise?

Yes. Hot air is less dense, and therefore lighter than cold air, so it will rise as cold air will drop. A perfect example of this, is smoking rising to the ceiling in a fire, or smoke rising out of your chimney.
