California has been experiencing drought since 2012, though 2017 has brought some relief in the form of torrential rains. These rains traveled to California in a series of atmospheric rivers, long narrow channels of water vapor in the atmosphere. These channels bring rainfall to the state when they are disrupted by atmospheric conditions over California's eastern mountains. This visualization...

An Emerald Vortex

Every so often, a vibrant green color infuses the waters of Lake Maracaibo. Floating vegetation—likely duckweed—was swirling in the Venezuelan lake when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite flew over in February 2017.

Most of the time, Maracaibo’s waters are stratified into layers, with nutrient-rich, cooler, saltier water at...

From an Atmospheric River to a River of a Sediment

In the past two months, weather reports in California, Oregon, and Washington have been filled with news of “atmospheric rivers” bringing copious amounts of rain and snow to the western United States. Atmospheric rivers are long, thin fingers of moisture that develop in the tropics and flow into higher latitudes. If one of them makes...

360 VIEW: Take a look inside the cockpit of NASA’s high altitude ER-2 aircraft as it descends for landing at Marine Corps Base Hawaii, Kaneohe Bay. This month scientists have been using the aircraft to collect data on coral reef health and volcanic emissions and eruptions. Flying at 65,000 feet, above 95 percent of Earth's atmosphere, the ER-2 has a unique ability to replicate the data a...

El Niño: Underwater Temperatures and Water Masses

The ocean is not uniform. Temperatures, salinity, and other characteristics vary in three dimensions, from north to south, east to west, and from the surface to the depths. With its own forms of underwater weather, the seas have fronts and circulation patterns that move heat and nutrients around ocean basins. Changes near the surface often...

Atmospheric river storms are common in winter along the U.S. West Coast, where rain and snow are often needed. For that reason, Americans tend to think of them mainly in terms of precipitation, imaged here. A new NASA study shows another risk along with flooding: high winds.

Researchers found that atmospheric rivers were associated with 14 (about 75 percent) of the most costly storms between...

6 Things You Didn't Know About Snow
NASA scientists are in the field right now, testing advanced technologies to measure snow like never before. In a five-year study called #SnowEx, researchers are improving techniques to determine how much water is stored in snow-covered regions around the world. More accurate snow measurements will help scientists and decision-makers better understand our...

Heat Wave Breaks Records in Australia

Heat waves are not unusual in Australia. A subtropical belt of high pressure that flows over the continent regularly delivers pulses of hot, dry air to the surface in the summer. Yet even by Australian standards, the intense heat wave of February 2017 has been remarkable.

When a high-pressure system stalled over central Australia, extreme temperatures...

Red on White: Lake Maharlu

An astronaut aboard the international Space Station took this photograph of the shores of Lake Maharlu in the mountains of southwest Iran. Yearly evaporation in this desert region is much greater than yearly rainfall so that, even with runoff from local rivers, the lake is often dry. And as with many desert lakes, salt has washed down from the surrounding mountains...

Beating Back the Sands in Isatay

Looking down from space in winter, the patch of earth around Isatay looks greenish brown—a misleading color. This remote part of Kazakhstan—a country with just 8 percent arable land—is far from verdant. In several parts of the country, desertification is a problem, often a result of overgrazing, farming practices, or aggressive land use in this arid climate....

Fires Threaten Christchurch

Fires near the center of Christchurch, New Zealand, have burned through homes and spurred the evacuation of more than 1,000 people, according to news reports. The seriousness of the Port Hills fires led officials to declare a state of emergency in the Selwyn District and in Christchurch, the largest city on New Zealand’s South Island.

The Moderate Resolution...

The Atmospheric Tomography (ATom) mission takes flight through Earth's atmosphere to understand how short-lived greenhouse gases like ozone and methane contribute to climate change. Flying over Hawaii, they also took readings of sulfur dioxide from the active volcano Kilauea, which creates "vog" -- a volcanic-type hazy fog that is a form of air pollution.
