Cold, Clouds, and Snowflakes
From NASA My NASA Data
Snow and ice are both precipitation, that is, the processes that remove water from clouds. Clouds, regions of the atmosphere with high relative humidity, are made of droplets of water and perhaps bits of ice. Even though water is much denser than air, these droplets and ice crystals are small enough to be suspended by random upward air motion. When these droplets or crystals join together, gravity overcomes the suspending force and we have precipitation. In this lesson, students will investigate NASA satellite data to determine geographical areas where wintry precipitation may have occurred based on cloud top temperature. They will explore the relationship between the amount of water vapor and the temperature of clouds, as well as snowflake shapes and cloud temperature.
