What two characteristics of thunderstorms that lead to hail formation?
It forms because of two characteristics common to thunderstorms. For hail to form, water droplets rise to the heights of a cumulonimbus cloud where the temperature is below freezing, encounter ice pellets, and freeze on contact with the pellets, which causes the ice pellets to grow larger.
What type of front would you expect to be associated with flooding Why?
What type of front would you expect to be associated with flooding? Why? a stationary front. they allow repeated thunderstorms to move across the same area.
What 2 conditions must exist for a tropical cyclone to form?
What two conditions must exist for a tropical cyclone to form? A very abundant supply of warm ocean water and a disturbance in the air.
What are the physical factors must exist for a tropical cyclone to form?
Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least 26.5 °C (79.7 °F)), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure center, a pre-existing low-level focus or disturbance, and …
What 3 conditions must be present for a thunderstorm to form?
There are three basic ingredients needed for thunderstorm development: moisture, an unstable atmosphere, and some way to start the atmosphere moving. Moisture is necessary to produce the thunderstorm clouds and precipitation.
How many thunderstorms are there?
How many thunderstorms are there? Worldwide, there are an estimated 16 million thunderstorms each year, and at any given moment, there are roughly 2,000 thunderstorms in progress. There are about 100,000 thunderstorms each year in the U.S. alone. About 10% of these reach severe levels.
Which front causes thunderstorms?
cold front
A cold front does the same thing with a warm air mass. The warm air is forced to rise because it is less dense than the cold air. This causes a surge of rising motion with is known to generate thunderstorms.
What type of thunderstorm tends to form with frontal weather?
Cold fronts occur when warm air is pushed up into the atmosphere by colder air at the ground. These fronts tend to move faster than the other types of fronts and are associated with the most violent types of weather such as severe and super cell thunderstorms, although any type of front can produce these same storms.
What conditions must exist for a thunderstorm?
How does a thunderstorm form?
Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere. There the moisture contained in the updraft condenses to form towering cumulonimbus clouds and, eventually, precipitation.
