What is causing the air in a storm to move?
The release of instability causes air to accelerate in the vertical. … The speed that is rises depends on the density difference between the air rising and the surrounding air. In any thunderstorm, rising motion is occurring since that air rising in the updraft of the storm is less dense than the surrounding air.
What are the two fast moving components that make up a derecho?
A typical derecho consists of numerous downburst clusters (“families of downburst clusters”) that are, in turn, composed of many smaller downbursts, microbursts, and burst swaths.
What causes storm surge?
Storm surge is caused primarily by the strong winds in a hurricane or tropical storm. The low pressure of the storm has minimal contribution! The wind circulation around the eye of a hurricane (left above) blows on the ocean surface and produces a vertical circulation in the ocean (right above).
What causes thunderstorms hurricanes and tornadoes to develop?
The ingredients are warm ocean water, weak upper level winds, and low pressure. The warm ocean water supplies the moisture for the hurricane. The weak upper levels winds allow the developing hurricane to not tear apart, and the low pressure allows thunderstorms to develop.
What front causes thunderstorms?
Large storm systems push that cold air southward and the leading edge of that cold air is the front. Cold fronts are notoriously known for their bad weather such as thunderstorms, tornadoes and heavy rain. Many of our severe weather events during the winter months are caused by cold fronts.
