Basic WX Training #4 – Thunderstorm Life Cycle
Life CyclePre-DevelopmentAs solar radiation begins heating the Earth's surface each morning, the daily convective cycle begins. In other words, air nearest to the surface begins heating, rising, cooling, falling, and so on. This motion "mixes" the PBL, allowing for air parcels to come closer and closer to their LCL. DevelopmentAfter…
Basic WX Training #3 – Thunderstorm Ingredients
DefinitionsUpdraftThe column of rising air associated with a freely convecting air parcel. In "air-mass" thunderstorms, the updraft is observable as a rapidly ascending cumulus tower (cumulus calvus). DowndraftA body of air which is descending due to a density differential (colder than surrounding air) and is accompanied by precipitation. Planetary Boundary…

Basic WX Training #2 – Temperature, Pressure, and Relative Humidity
DefinitionsAir Parcel:Meteorologists use the term "parcel" to describe a single unit of measurement for air in the atmosphere. Think of this unit as a large "bubble" of air, about the size of neighborhood (for mesoscale, or "thunderstorm scale" phenomena). Temperature (T):The measure of the average energy content of…
Basic WX Training #1 – Levels of the Atmosphere
DefinitionsThe atmosphere is a fluid body which extends from the Earth's surface to a variable height of about 600 miles and consists of several layers of gasses, water, and aerosols.Levels (lowest –> highest)TroposphereExtends from the surface to 8-14.5 km (5-9 mi)About 90% of the atmosphere's mass…
