Weather & Airplane Crashes

Weather for PilotsWith 0 comments

Weather & Airplane Crashes has been an issue of late. First, let us give some perspective and these statistics were compiled from 1,015 fatal accidents, excluding those involving less than 19 passengers, military aircraft, private aircraft and helicopters. Airplane crashes, on average, claim the lives of a thousand passengers every year. Crashes happen for many

How Midwestern blizzards are born

General Info, Poor VisibilityWith 0 comments

How Midwestern blizzards are born. A Midwestern blizzard, the most common type, is born when a cyclonic, deep low spins next to a very cold, very high-pressured anticyclonic Canadian air mass while it pushes southeasterly into the upper Midwest. If the pressure gradient between the two air masses tightens, wind speeds increase. Moisture in the

The Life Cycle of Hail

General InfoComments are off

Hail originates as tiny cloud droplets with diameters of 0.02 mm. After large masses of these droplets are sucked into updrafts, they elevate to heights that are much colder than the surface. Their rapid transport and the lack of ice nuclei in their paths cause them to cool below 0°C without freezing (supercool.) Soon, additional

Tornadogenesis: How Tornadoes Form

General Info, Historical Weather Data, Microburst, Weather ConditionsComments are off

Before tornadoes, there exist mesocyclones: giant, rotating columns of low-pressure air that sink below the height of their surrounding cloud basins. Sometimes subsidiary vortices called tornadoes spawn under them. The already swiftly-moving air circulating above is restrained into a smaller diameter and, due to the conservation of angular momentum, wind speed is increased. If the
