Weather Spotter’s Field Guide - Types of Thunderstorms
Types of Thunderstorm. Thunderstorms can be categorized by their physical characteristics: the presence or absence of rotation, the number of location of updrafts and downdrafts present. There is a continuous spectrum of types of storms that we observed.
Weather Fronts - Center for Science Education
At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed. A weather front is a transition zone between two different air masses at the Earth's surface. Each air mass has unique temperature and humidity characteristics.
Cold front - Wikipedia
Cold fronts are the leading edge of cooler air masses, hence the name "cold front". They have stronger temperature changes during the fall (autumn) and spring, and during the middle of winter. Temperature changes associated with cold fronts can be as much as 30 °C (54 °F).

How Do Cold Thunderstorms Happen? - WeatherBug
Oct 28, 2022 · How do thunderstorms form when it's that cold? The most common "cold" thunderstorms are known as elevated thunderstorms. These storms can occur when it is cold at the surface, but there is a warm layer higher up in the …
Weather front - Wikipedia
For instance, cold fronts can bring bands of thunderstorms and cumulonimbus precipitation or be preceded by squall lines, while warm fronts are usually preceded by stratiform precipitation and fog. In summer, subtler humidity gradients known as dry lines can trigger severe weather.
THUNDERSTORMS - National Weather Service
COLD FRONTS: Cold fronts tend to be the fastest movers compared to the other front types. This fast movement increases convergence along the front and results in faster storm movement, if storms do develop. The slope of a cold front is greater than that of the other frontal types.
Cold Front - Definition, Symbol, Characteristics, & Diagram
Jan 13, 2025 · A cold front occurs when a mass of cold, dense air moves into an area of relatively warm, light air, forcing the warm air to rise. Depending on the season, this can lead to noticeable weather changes, such as a drop in temperature, increased cloud formation, and precipitation, such as rain, thunderstorms, or even snow.
Cold Fronts | METEO 3: Introductory Meteorology - John A.
Thus, showers and / or thunderstorms often precede the passage of a cold front (although not as often in the winter). In the wake of the front, cold-air advection tends to promote currents of sinking air, which helps cause clouds to evaporate, promoting clearing or partially clearing skies.
Thunderstorms - Center for Science Education
Frontal thunderstorms are caused by the upward lifting of air along a storm front. Frontal thunderstorms can occur along the boundary of a weather front (e.g., a cold front). Air mass thunderstorms form when warmer, wetter air within an air mass is lifted upward.
