Was the relationship among temperature, heat, and thermal energy?

What will most likely happen when a warmer air mass exists above a polar ice sheet? The temperature of the ice sheet will be lowered. Heat will be transferred from the air mass to the ice. The air mass will exert high pressure and rise upwards.
