What Is a Climograph?

According to National Geographic, a climograph is a graphic representation of climate information. It is considered a useful tool for studying climate and its effects on the human environment.

A climograph allows a researcher to plot the amount of rain and the temperature over a set period of time, usually over the course of a year. The Center for Educational Technologies explains that a climograph contains two vertical axes and one horizontal axis. The first vertical axis measures the amount of rainfall (usually in inches), while the monthly temperature is plotted against the second vertical axis. The horizontal axis shows the time frame that is being researched. A bar chart is used to show average monthly rainfall, and a line graph is used to show average monthly temperature.
