Water in the World: Rainfall

There are three different types of rainfall: relief (or orographic), convectional and frontal. Read through this website to learn more about different types of rainfall, and how they present in the UK.

Read through this website to learn about the different tools and methods used for measuring rainfall.

Rainfall is both a needed resource, since it fills rivers and provides fresh water, and a potential threat with heavy rainfall leading to (possibly rapid) flooding. A much needed step to understand better this natural phenomenon is to properly measure it. It turns out to be pretty tricky because rainfall is extremely variable in time and space. In this paper, you will learn the functioning of three rainfall measurement devices providing cumulative rainfall depth (tipping bucket rain gauges), size and velocity of falling drops (disdrometers), or rainfall maps (weather radars).

Read through this resource to learn more about climate graphs and how to read them.

Climate graphs are used to illustrate the average temperature and rainfall experienced at a particular place over the course of a year. The graphs consist of a red line graph showing average monthly temperature, and a simple column graph showing average monthly rainfall figures. Rainfall is, by tradition, shown in blue.
