SCIENCE OF STORMS: ASSIGMENT 4 Jawad Islam 260353581 1> Lake-effect snow is produced in the winter when cold winds move across long expanses of warmer lake water, providing energy and picking up water vapor which freezes and is deposited on the leeward shores. Any large body of water upwind will impact lake-effect precipitation to the lee of a downwind lake by adding moisture or pre-existing lake-effect bands, which can re- intensify over the downwind lake. Upwind lakes do not always lead to an increase of precipitation downwind. On the upwind side the relatively cold air is stable as it has not been warmed sufficiently by passing over the lake. As the air continues to move across the relatively warm lake the air is warmed by contact enough that it begins to rise and eventually form clouds. 2> Snowflakes are conglomerations of frozen ice crystals which fall through the Earth's atmosphere. They begin as snow crystals which develop when microscopic super cooled cloud droplets freeze.
