Document Summary
Comes in liquid/solid forms of water that are coming back to the ground from the clouds. Important: snow melts at 0 degrees (stays as snow when it remains at a temperature of 0 and will begin to melt at temperatures above 0 degrees: lake effect snow. Cold dry air from the north/prairies moves over cool land. Warm lake releases heat as water vapour. On maps, orange and red spots mean dense precipitation. Everything has 1 meter of snow covering it: hail. Eventually the force of gravity will pull the hail stones to the ground. Formation of small ice crystals at 5 km. Bigger ice crystals as they start to descend (water droplets freeze onto the ice) Lower water content = temps above 0c; rain or snow. High water content in cloud: above 0c; rain or hail. Both types of clouds have rain when temp is above 0c. Rate of cumulonimbus precipitation is more than nimbostratus: acidification.
