There are a number of tools and types of forecasts meteorologists use every day. However, forecasts are never perfect. In general, the further out a forecast goes, the more fine details are lost. This is because the complex equations and programs that create our weather models are time-dependent. The programs essentially act like a giant

There are a number of different astronomical calendars. They are lunar calendars, lunisolar calendars, and solar calendars. Lunar Calendars are based solely on the cycles of the moon. Since one lunar month is 29.5 days, a lunar year is about 354 days. Credit: Chris Casas A lunisolar calendar is still based on the moon but

There are thousands of weather stations across every corner of the country recording values such as temperature, pressure, moisture, and of course, precipitation. But how do meteorologists measure rain so that an inch of rain in Palm Springs is the same as an inch of rain in Miami, New York, Chicago, or anywhere else around

Mudslides are a hazard caused by heavy rains. There are layers of soil under our feet. The further down a layer of soil is, the more compressed and stable it becomes. When the topsoil becomes saturated with rain, it becomes heavier. This, combined with the flowing water, can lead to that top layer of soil

Atmospheric rivers play a critical role in transporting water throughout the atmosphere by advecting (moving) moisture from the tropics to higher latitudes. When fully developed, they can deliver widespread rain and snow to areas all along the west coast. If an atmospheric river originates in Hawaii, like shown below, it is called a ‘Pineapple Express’.
