The latent heat released during condensation in a saturated air mass slows the rate of adiabatic cooling. The latent heat is stored as air descends and warms, increasing the wet adiabatic lapse rate to the dry adiabatic lapse rate.

Snow reflects more solar radiation than seawater does, so it has a higher ____.

albedo

Why are high-pressure systems common over land in winter, while low-pressure systems are common over neighboring oceans? Winter upwelling of water forces the air above the oceans to rise, and that pulls in the air off the land to replace the uplifted air. Snow and ice cover on land lowers the albedo far enough to cause cooling and then sinking of air masses above the land which then blow to the ocean. The relatively warmer ocean causes the air above it to rise, while the cooler land has air sinking above it. The relatively warmer land causes expansion in the air above it, causing winds to blow onto the land from the ocean. The low angle of the sunlight is easily reflected by the water, causing the air above to rise, while poor reflection on land causes the air to sink.

The relatively warmer ocean causes the air above it to rise, while the cooler land has air sinking above it.
