Meteorology (Weather)/Blizzard swath
I'm a novelist writing a scene where an aircraft is flying into a blizzard. Question: How high or tall can a extraordinary blizzard reach? Is a 1000 feet too high?
Hope to hear from you soon.
There are two types of blizzards. One being a "ground blizzard" where the source of snow is previously fallen and being blown around by gale force winds of 35 mph or more with visibilities less than a quarter mile for 3hours or more. This type of blizzard would be confined to close to the ground, i.e., less than 1000 feet.
The second type of blizzard is a storm, low pressure area, that has the same conditions of a "ground" blizzard except the snow is precipitating from clouds several thousand feet above the ground.
