What is different about the conditions when hail, snow, and sleet form compared to when rain forms?
Answer:
Sleet forms in winter storms, while hail is a warm-season type of precipitation. As noted above, sleet forms when snow melts in a warm layer and then refreezes into ice pellets as it falls though a cold layer. Hail, however, forms in spring, summer or fall thunderstorms.
Explanation:
Hail, snow, sleet, and rain are all forms of precipitation that form under different atmospheric conditions. The main difference between the conditions required for hail, snow, sleet, and rain formation is the temperature and the type of clouds involved.
What are Hail, snow, sleet, and rain?Rain forms when the air temperature is above freezing and water droplets in the atmosphere combine to form larger droplets that are heavy enough to fall to the ground. This typically occurs in large cumulonimbus clouds associated with thunderstorms, where the upward motion of air currents keeps the droplets aloft until they grow large enough to fall to the ground.
Snow forms when the air temperature is below freezing and the water vapor in the atmosphere directly forms ice crystals instead of liquid droplets. These ice crystals then grow larger as they move through the atmosphere, eventually falling to the ground as snowflakes.
Sleet forms when the air temperature is near freezing and rain droplets fall through a layer of freezing air near the ground. The rain droplets freeze into ice pellets before hitting the ground.
Hail forms when the air temperature is warm near the ground, but there is a layer of cold air higher up in the atmosphere. This creates strong updrafts in thunderstorm clouds that carry rain droplets upward into the colder air, where they freeze into ice pellets. These pellets can then fall back into the warm air and melt slightly before being carried back up into the colder air, where they refreeze and grow larger. This process can repeat multiple times, creating hailstones of different sizes before they fall to the ground.
Therefore, the differences in atmospheric temperature, the presence of freezing air layers, and the type of clouds present all play a role in determining whether precipitation falls as rain, snow, sleet, or hail.
