Hail is a form of precipitation consisting of solid ice that forms inside thunderstorm updrafts. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. What we do: …

Jan 13, 2025 · A weather front is a zone of transition between two different air masses at the Earth’s surface. Each air mass has unique characteristics like density, water content, and temperature. Thus, at each front, there is always a disturbance, which often …

Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth's surface.

Jan 19, 2024 · Warm fronts occur when a warm air mass advances and replaces a colder body of air, covering the colder air from the top and forcing the cold air out below. This type of front moves slowly, typically at about 10-25 miles per hour. Generally, as this air is forced upwards by the frontal change, stratiform and cirriform clouds and fog can be expected.

May 12, 2020 · Hailstones are formed when rain droplets are carried upwards by a current of air, called an updraft, during thunderstorms. “Hail forms as robust thunderstorms grow taller and taller, lofting...

Oct 16, 2024 · Understanding weather fronts is crucial for forecasting extreme weather, such as tornadoes, flash floods, and winter storms. Meteorologists use advanced satellite imaging, …

Three-body scatter (hail) spike indicates large hail in storm (area of high reflectivity). Surface hail size is a function of initial diameter, thermal profile to ground, and location of hail vs. heavy rain shaft.

Fronts bring changes in temperature, dew point, winds and pressure. They can also bring precipitation. Select each type of front below, then click-and-drag to see how it brings different weather conditions. To learn more about the type of front, click on the name.

NSSL researchers make computer models of entire hailstorms (air currents, temperature, water substance, precipitation and hail contents and size distributions) via state-of-art cloud models. …

Nov 2, 2024 · The National Weather Service defines hailstorms as storms that produce hail with a diameter of at least 5 mm (0.2 inch). Hailstorms cause damage to homes, cars, and aircraft, and can be dangerous if hailstones are large enough to cause injuries to people.
