Thunderstorms in an atmosphere with virtually no vertical wind shear weaken as soon as they send out an outflow boundary in all directions, which then quickly cuts off its inflow of relatively warm, moist air, and kills the thunderstorm's further growth. [19] The downdraft hitting the ground creates an outflow boundary. This can cause ...
Dust storms cause soil loss from the drylands, and worse, they preferentially remove organic matter and the nutrient-rich lightest particles, thereby reducing agricultural productivity. Also, the abrasive effect of the storm damages young crop plants. Dust storms also reduce visibility, affecting aircraft and road transportation.
Air pollution can cause diseases, allergies, and even death; it can also cause harm to animals and crops and damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). [2] Air pollution can occur naturally or be caused by human activities. [3]
The Sun warms the ground, which in turn warms the air directly above it. The warmer air expands, becoming less dense than the surrounding air mass, and creating a thermal low. [4] [5] The mass of lighter air rises, and as it does, it cools due to its expansion at lower high-altitude pressures. It stops rising when it has cooled to the same ...
A storm seen at the Baltic Sea near the island of Öland, Sweden.. A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body. [citation needed] It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain ...
Areas like the Midwest and South see a lot of thunderstorms because moisture-heavy air from the Gulf of Mexico travels northward, providing plenty of unstable energy in the atmosphere. That warm ...
Although heat waves do not cause as much economic damage as other types of severe weather, they are extremely dangerous to humans and animals: according to the United States National Weather Service, the average total number of heat-related fatalities each year is higher than the combined total fatalities for floods, tornadoes, lightning ...
As the atmosphere remains stuffed with tropical moisture, AccuWeather meteorologists are warning that more incidents of life-threatening flash flooding can occur in parts of the Northeast. As has ...
