What Is The Definition Of A Thunderstorm - ANS Any Storm That Produces Thunder
(Lightning Required), Convective And Form In Unstable Environments
What Are The Characteristics Of An Ordinary (Single Cell) Thunderstorm? - ANS Lasts Less
Than 1 Hour, Has Weak Vertical Wind Shear, Shallow Zone Of Wind Convergence, And Goes
Through 3 Stages: Cumulus, Mature, Dissipating.
What Defines A Multicell Thunderstorm? - ANS A Cold Downdraft Reaches The Surface,
Forcing Warm Moist Air Upward; Consists Of A Series Of Thunderstorms In A Line; Requires
Strong Wind Shear.
What Are The Key Features Of A Supercell Thunderstorm? - ANS Very Strong Vertical Wind
Shear, Downdraft Never Undercuts Updraft, Creates Rotation, Lasts A Long Time, And Can
Produce Tornadoes.
How Does Moisture Help Increase Instability? - ANS Latent Heat Release Of Condensation
Makes The Moist Adiabatic Lapse Rate Less Steep Than The Dry Rate. So, A Rising Parcel Will
Stay Warmer In The Environment For Longer
What Are The Three Critical Ingredients Necessary For Thunderstorm Formation? - ANS 1.
Moisture
2. Instability

, 3. Lift
In What Wind Shear Conditions Do Ordinary Thunderstorms Occur? - ANS Weak
Where Are Ordinary Thunderstorms Common - ANS Many Areas Including SE US In The
Summer
What Are The Cumulus, Mature, And Dissipation Stages? - ANS Cumulus: Small Cumulus
Clouds Bubble Up Into A Conditionally Unstable Atmosphere, Gradually Moistening The
Atmosphere Above For Deeper Clouds
Mature: Rising Parcels Are Neutrally Buoyant, Anvil Is Formed, Rain Is Generated Along With
Updraft And Downdraft
Dissipation: Precipitation And Evaporative Cooling Weaking The Updraft And Generate A More
Stable Atmosphere
What Are The Updraft And Downdraft, And How Are They Formed? - ANS Updraft Is The
Convective Warm Moist Rising Air Parcels. Downdraft Is Due To Evaporative Cooling And The
Less Buoyant Air Sinks
How Does The Storm Die? - ANS There Is No Source Of Surface Warm, Moist Airremaining To
Generate Positive Buoyancyand Convective Updrafts In The Storm
Why Does The Downdraft Sink? Or Alternatively, Why Are Thunderstorm Outflows (Cold Pools)
Cold? - ANS Evaporation Of Raindrops Steals Heat From The Environment, Cooling The
Surrounding Air. The Cool Air Sinks And Spreads Out When It Gets To The Surface.
What Is A Gust Front? - ANS Leading Edge Of Cold Air Coming From The Downdraft Hitting
The Surface And Spreading Out
What Is The Anvil Of A Thunderstorm - ANS Section Of The Top Of A Cumulonimbus Cloud
That Spreads Out Horizontally As It Hits The Tropopause
