Sleet: Explanation and Study Guide
Sleet is a type of precipitation that occurs when raindrops freeze before reaching the ground. It is often associated with winter weather and can create hazardous conditions on roads and walkways.
Formation of Sleet
Sleet forms when warm air above the ground melts snowflakes into raindrops. These raindrops then pass through a layer of freezing air near the surface, causing them to freeze into small ice pellets before reaching the ground.
Characteristics of Sleet
- Sleet appears as small, translucent ice pellets.
- It can accumulate on the ground, creating slippery surfaces.
- Sleet often occurs in conjunction with freezing rain and snow.
Study Guide
When studying sleet, consider the following key points:
- Understand the conditions required for sleet formation, including the presence of warm air aloft and a layer of freezing air near the surface.
- Learn about the hazards associated with sleet, including its impact on travel and infrastructure.
- Compare and contrast sleet with other forms of precipitation, such as snow and freezing rain.
- Explore the regional and seasonal patterns of sleet occurrence.
