Question

6 pts Question 34 Match the type of lake effect snow with its respective definition. Wind-parallel rolls [Choose] Shore-parallel bands [Choose] Vortices (Choose]

Answer 1

First option is correct. Lake effect snow is narrow short band of precipitation that appear on radar as parallel bands of precipitation.

Lake effect snow, which can be a type of snowfall, is produced in the winter when cold winds move across long expanses of warmer lake water, picking up water vapor which freezes and is deposited on the lee shores.

This effect is enhanced when the moving air mass is uplifted by the orographic effect of higher elevations on the downwind shores.

This uplifting can produce narrow, but very intense bands of precipitation, which deposit at a rate of many inches of snow per hour.
