Dry thunderstorms occur essentially in dry conditions, and their lightning is a major cause of wildfires. [ 3 ] [ 4 ] [ 5 ] Because of that, the United States National Weather Service , and other agencies around the world, issue forecasts for its likelihood over large areas.
The actual phenomenon that is sometimes called heat lightning is simply cloud-to-ground lightning that occurs very far away, with thunder that dissipates before it reaches the observer. [2] At night, it is possible to see the flashes of lightning from very far distances, up to 100 miles (160 km), but the sound does not carry that far. [3]
The Norse considered thunderstorms to occur when Thor went to fight Jötnar, with the thunder and lightning being the effect of his strikes with the hammer Mjölnir. Hinduism recognizes Indra as the god of rain and thunderstorms. Christian doctrine accepts that fierce storms are the work of God.
Thunder is the sound caused by and after lightning. [ 1 ] [ 2 ] [ 3 ] Depending upon the distance from and nature of the lightning, it can range from a long, low rumble to a sudden, loud crack. The sudden increase in temperature and hence pressure caused by the lightning produces rapid expansion of the air in the path of a lightning bolt . [ 4 ]
Thundersnow can occur during a normal snowstorm that sustains strong vertical mixing which allows for favorable conditions for lightning and thunder to occur. It can also occur from the lake effect or ocean effect thunderstorm which is produced by cold air passing over relatively warm water; this effect commonly produces snow squalls over the ...
Thunderstorms that ignite on the fringe of the heat dome are known as ring of fire thunderstorms. "You hear the 'ring of fire' when we talk about volcanoes in the Pacific," AccuWeather Chef On-Air ...
The two major ways thunderstorms move are via advection of the wind and propagation along outflow boundaries towards sources of greater heat and moisture. Many thunderstorms move with the mean wind speed through the Earth's troposphere , or the lowest 8 kilometres (5.0 mi) of the Earth's atmosphere .
Santa Ana winds occur when winds blow and pick up speed as they travel from the inland deserts toward the coast. These wind events usually kick off in the fall and winter months in the Los Angeles ...
