How does air pollution affect clouds?

The researchers also found that because smoke particles block out the sun, preventing moisture from evaporating, it prevents clouds from forming. Like smoke blocking out the sun, the team also discovered that that high levels of pollution creates a similar atmospheric effect and hinders cloud growth.

Does pollution affect rainfall?

The adverse effects of air pollution on human health are well-established. Now, scientists agree that pollutants interfere with the differential heating of land and sea and reduce the country-wide rainfall by at least 10 per cent and also cause extreme weather events like unusually heavy rainfall.

Do clouds form because of pollution?

NASA scientists have determined that the formation of clouds is affected by the lightness or darkness of air pollution particles. This also impacts Earth’s climate. “When the overall mixture of aerosol particles in pollution absorbs more sunlight, it is more effective at preventing clouds from forming.

Does more pollution mean more rain?

Writing in the journal Science, the scientists said pollution can both increase and decrease rainfall depending on local environmental conditions. With rising pollution, the amount of rain at first rises, then maxes out, and finally falls off sharply at very high aerosol concentrations, they concluded.

Can stratus clouds produce rain?

Stratus clouds are uniform and flat, producing a gray layer of cloud cover which may be precipitation-free or may cause periods of light precipitation or drizzle. Thick, dense stratus or stratocumulus clouds producing steady rain or snow often are referred to as nimbostratus clouds.

How does air pollution cause rain?

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Does air cause rain?

Clouds and rain occur when moist, warm air rises from ground level and water condenses or freezes on aerosol particles in the air.

How does wind weather affect air pollution?

Low pressure systems bring wet and windy conditions. A passing storm front can wash pollutants out of the atmosphere or transport them to a new area, producing clear skies. It is important to note, however, that the pollutants are not really gone, rather they have been moved to a new location.

What happens to the air when it rains?

As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, and organic particles.

What clouds cause rain?

The prefix “nimbo-” or the suffix “-nimbus” are low-level clouds that have their bases below 2,000 meters (6,500 feet) above the Earth. Clouds that produce rain and snow fall into this category. (“Nimbus” comes from the Latin word for “rain.”) Two examples are the nimbostratus or cumulonimbus clouds.

What causes clouds to release rain?

Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.
