Weather Things: Storms
The atmosphere is dynamic and forever changing to maintain balance. The ingredients of air, sunlight and water allow life to exist on Earth, but they also generate calm scenes like rainbows, as a tornado ends. All storms move moisture,...

Why Do Raindrop Sizes Matter In Storms?
Not all raindrops are created equal. The size of falling raindrops depends on several factors, including where the cloud producing the drops is located on the globe and where the drops originate in the cloud. For the first time,...

NASA | A Week in the Life of Rain
Rain, snow, hail, ice, and every slushy mix in between make up the precipitation that touches everyone on our planet. But not all places rain equally. Precipitation falls differently in different parts of the world, as you see in NASA's...

NASA’s New View of the Daily Cycle of Rain
The most detailed view of our daily weather has been created using NASA's newest extended precipitation record known as the Integrated Multi-satellitE Retrievals for GPM, or IMERG analysis. The IMERG analysis combines almost 20 years of...

NASA Peers Inside Hurricane Edouard
The swirling nature of hurricane clouds are a familiar sight in satellite imagery, but in order to better understand these storms, scientists need to look inside them. In 2014, NASA's remotely piloted Global Hawk aircraft flew over...

NASA | For Good Measure
The need for measuring the when and where and how much of precipitation goes beyond our weekend plans. We also need to know precipitaiton on a global scale. Rain gauges and radars are useful but are inconsistent and do not cover enough...

Water Smart: Water on Earth - Lakes
Water on Earth focuses on water as most kids would think about it. We start with water in obvious locations such as oceans, lakes, and rivers. We quickly learn that water can change phase to remain a solid in glaciers. Many kids may be...

The Common Ion Effect
We've learned a few applications of the solubility product, so let's learn one more! This is called the common ion effect, and it can be a good way to influence the solubility of a particular ionic compound in solution, or even promote...
