Sentences with word «mesoscale»
"mesoscale" refers to something that is in between small and large scales. It describes phenomena or measurements that occur on a middle level, typically ranging from a few kilometers to a few hundred kilometers in size. For example, weather patterns or wind systems that affect a city or a small region can be considered mesoscale. It is a way to describe things that are not too small or too big, but somewhere in the middle. Full definition
