Answer: Clouds form when sufficiently moist air is cooled to the dew point temperature of the air or below, so that either liquid water droplets form on cloud condensation nuclei, or in the case of ...

To produce lake effect snow, the air temperature 5,000 feet high needs to be at least 23 degrees Fahrenheit colder than the water temperature, and the air temperature 10,000 feet up needs to be at ...

There are two ways snow can begin to form in clouds. When the air is very cold, water vapor can convert directly to ice through a process called “homogenous nucleation.” At temperatures between minus ...

Snow is the classic of any winter precipitation and forms when temperatures are at or below freezing in the cloud and at to ...

The Basic Building Blocks Every Cloud Needs Clouds need two essential ingredients to form, and both must be present ...

When towns along the Great Lakes get buried in drifts of blowing snow, like several have over the past few days, weather experts start talking about the “lake effect.” Lake-effect snow often occurs in ...

This causes repeated rounds of cold air to spill over the Great Lakes and create bands of heavy lake-effect snow off lakes ...
