WEAX 201 Module 8 Study Guide Exam 2024-2025Conditionally unstable - Answer Thunderstorms are convective sotrms containing
lightning and thunder, developing when a relatively warm, humid (high dew point) air
rises to saturation within a_______ ________ environment.
Surface heating and convection
Lifting along a frontal zone, outflow boundary, or topography
Surface convergence and/or upper level divergence - Answer Trigger mechanisms that
start air moving upward to the point of saturation could be one or a combination of the
following.
Florida - Answer Has the highest frequency of thunderstorms in the United States
The Pacific coast - Answer Has the lowest frequency of thunderstorms in the United
States
The Great Plains - Answer Conditions over ___________are more favorable for the
development of severe thunderstorms, especially supercells, with strong updrafts.
Ordinary thunderstorms
Severe thunderstorms - Answer The two main categories of thunderstorms
Ordinary thunderstorms - Answer Short-lived (less than 1 hour)
Severe thunderstorms - Answer Develop at least one of the following:
*Largest hail ( >1 in. diameter)
*Surface wind gusts greater than or equal to 50kts (58 mph)
, *A tornado
Vertical wind shear - Answer Severe thunderstorms have longer life spans than ordinary
thunderstorms because of the presence of significant___________.
De-stabilized - Answer Short-lived storms which tend to form in the afternoon when near
warm, moist, near-surface air is ______by daytime heating.
Conditions for formation - Answer *Weak upper level winds (low vertical wind shear)
*Tend to form along shallow zones where surface air converges such as:
1. Sea Breeze Fronts
2. Cold outflow from another thunderstorm
3. Topographic irregularities
Cumulus (growth) stage
Mature stage
Dissipating stage - Answer What are the three stages of an ordinary thunderstorm?
Cumulus (growth) stage - Answer 1. Rising, condensing humid air mass forming a single
cumulus cluster.
2. Great amounts of latent heat is released during the condensation of the air that keeps
the cloud warmer than the ambient and enables the cloud to grow upwards as towering
Cu and finally as Cb.
3. The droplets of water grow larger and heavier and fall creating a downdraft inside the
cloud, this is the beginning of maturity.
Mature stage - Solution fully developed stage.
This continues until the cloud reaches the tropopause, at which time it spreads
horizontally when overshooting into the relatively warm air of the stratosphere, creating
an anvil cloud. Precipitation reaches the ground as heavy rain and possible hail.
3. Precipitation is preceded by a strong downdraft, which is COLD due to the
evaporation of raindrops by drier air entrained into the cloud, and the melting of falling
