The study looked at how moisture and heat move between grassland and bare soil in a dry area to understand sandstorms better. They used a method called eddy covariance to measure these movements. During sunny days, the grassland released more water vapor (latent heat) than heat (sensible heat). But the bare soil gave off more heat than water vapor. Even on cloudy days, the grassland still let out more water vapor. Grasslands help cool down and add moisture, which is good for the environment. This can help prevent sandstorms and keep nature balanced.
