A is warm moist airB is the anvil C over shooting top D heavy rainE cold dry airF tropopauseThunderstorms are also known as cumulonimbus cloudsMost damage due to sever thunderstroms is concentrated in the Central Plains and east of the MississippiNational weather service criteria for a sever thunderstorm can include one of the following- Hail with ¾ inch diameter- Win damage or wind gusts > 58 mph- Tornado Necessary ingredients for the formation of a thunderstormSource of moistureMechanism to trigger updraftConditionally unstable atmosphereMesoscale refers to a few kilometers to a few hundred kilometersSupercell thunderstorms always rotate All thunderstorms have anvilsGust fronts develops when cool air generated by evaporation of rain within the downdraft spreads outward away from the thunderstorm after reaching the surfaceOvershooting top is the term used to describe the bulge at the top of the thunderstorm cause by a strong updraftCold pool described the accumulation of rain-cooled air near the surface, under a thunderstormAirmass thunderstorms tend to occur in environments where the winds do not increase substantially with heightAir mass thunderstorms would most likely form far away from frontal boundaries close to 4:00 PMStrong winds cause the updraft to tilt and separate from the downdraft, allowing inflow of war, moist air to continue to feed to storm, and that is why wind shear is a key environmental condition for sever thunderstorm formation Tornadoes: - primarily develop within super cell thunderstorms- form in thunderstorms along squall lines, near the ends of thunderstorm bowechoes and within land-falling hurricanes- typically range in width form about 150ft to ½ a mileSuper cell rotation develop as a result of tilting and stretchingVortices form smallest to largestSuction vortex tornado mesocyclone hurricane extra tropical cycloneIn a super cell thunderstorm a tornado develops coincident with the location of the updraft part of the thunderstormA supercell thunderstorm develops along a dry line associated with a cyclone, An EF4 tornado emerges from the super cell. A sever storm spotter observes suction vortices. Which vortex has the strongest winds within the weather system? Suction vortex. Tornadoes do not develop from all mesocyclones. What is the current estimate basedon statistics of the present of super cell thunderstorms that produce distinct mesocyclones signatures on radar and produce tornadoes? 30%If a super cell is producing a tornado, the tornado would be found in the cusp of the “hook echo: what weather product would a meteorologist examine to observe the hook echo? Radar reflectivity image Landspouts are generally short livedSupercell tornadoes are typically stronger then land sproutsMost tornadoes that occur in California in winter are landspoutsLandspouts develop along a boundary where horizontal wind shear is present Most tornadoes in California are landspouts The great plain is the region with the largest # of reported
