As the planet warms, rainfall and weather patterns will change. As temperatures rise, the amount of water in the atmosphere will increase. Some areas will become wetter, while others, like southern ...

While the Upper Ohio Valley is no stranger to heavy rainfall and flooding, the conditions that have been in place over the past couple of days have supercharged the atmosphere to produce some ...

There are many ways to measure moisture in the atmosphere including relative humidity and dew point. Another way you may not have heard about is called precipitable water and meteorologists use this ...

Imagine wringing out the entire atmosphere like a sponge; how much water would fall? That’s what precipitable water tells us. Precipitable water (often abbreviated as PWAT) is a measure of how much ...

The term precipitable water is what the depth of all of moisture in the troposphere would be if it were condensed and deposited on the Earth’s surface. It is mathematically determined by integrating ...

NORFOLK, Va. — Meteorologists use several tools at their disposal that help to determine the amount of moisture that is present in the atmosphere at any given time. Two recognizable examples of this ...

The term precipitable water is what the depth of all of moisture in the troposphere would be if it were condensed and deposited on the earth’s surface. It is mathematically determined by integrating ...

A key finding was that urban flood events are often associated with extremely high Precipitable Water (PW) and often exceed the 99th percentile of the dataset. In other words, it is a top 1% event.

The title above refers to a parameter that meteorologists use to judge the overall moisture content of an airmass, and we had a rather moisture laden airmass with fairly high precipitable water (PW) ...
