Climate is the pattern of weather a place has over a long period of time. People who study climate are called climatologists. What do these scientists look for when they study a region's climate? Some of what they measure include average rainfall, sunshine, winds, and temperature. They also look at how each weather condition changes from month to month and year to year. For example,are there cold and hot seasons in the region? Or do the temperatures stay pretty much the same all year long? Does it rain more during certain months than others?
