Jan 17, 2025 · By studying these winds, scientists can learn more about ocean processes and improve predictions of extreme weather. NASA’s available data products useful to the study of surface winds include average wind speed and direction, sea level pressure, and surface stress.

Jan 23, 2025 · Atmospheric Winds NASA’s atmospheric wind data provide measurements to profile the force of nature over land, water, and high into the sky. Wind moving through Earth’s atmosphere from 30,000 feet high in the jet stream to breezes near the ground shape the planet, drive its weather, and constantly factor into our everyday lives.

Jul 28, 2020 · Winds over the oceans are retrieved because the water's surface roughens rapidly with increasing wind speed, which increases the backscatter detected by this specialized radar instrument. NSCAT scans two 600 km bands of the Earth -- one band on each side of the instrument's orbit path, separated by a gap of 330 km.

Dec 7, 2023 · Model simulations of a storm-force MGW event over the Gulf of Tehuantepec. Top plot represents the spatial distribution of 10-meter winds (in meters per second) if ocean-atmosphere effects are not included in the forecast model, and bottom plot shows simulation results if ocean-atmosphere effects are included in the forecast model.

Status. This activity is currently in pre-formulation and aims to combine wind retrievals from Advanced Scatterometer (ASCAT)-B/C, Sentinel-1, Radar Satellite (RADARSAT) 2, NASA/Indian Space Research Organisation Synthetic Aperture Radar (NISAR), Advanced Land Observing Satellite (ALOS)-4, Surface Water and Ocean Topography (SWOT), commercial SARs, Compact Ocean Wind Vector Radiometer (COWVR ...

MEaSUREs 2017 project focused on a data record of ocean surface winds as observed by the Ku-band pencil beam (NASA/ISRO) and C-band push-broom (EUMETSAT). Creating an Extended and Consistent ESDR of the Ocean Surface Winds, Stress, and Their Dynamically-Significant Derivatives for the Period 1999-2022 | NASA Earthdata

Jan 17, 2025 · Hurricanes are a rotating, tropical cyclone with a low pressure center (the eye) and 1-min average surface (10 m) winds in excess of 32 m s−1 (64 knots) in the Western Hemisphere. This area encompasses the North Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and the eastern and central North Pacific east of the international date line.

The winds funnel through the Chivela Pass, a narrow gap in the Sierra Madre Mountains. This forces the winds to accelerate, much like air hisses out of a tire leak. The winds emerge as a wind jet with speeds in excess of 20 meters per second (45 miles per hour). For this reason, scientists call the Tehuano a coastal gap wind jet, or simply gap ...

Dec 28, 2020 · Heavy winds and stormy seas cause the cargo ship Rena to run aground on October 5, 2011, spilling its cargo and eventually sinking. (Courtesy Blue Elf/Wikipedia) Still, the question remained: What was the risk that a vessel like the München would encounter catastrophic waves?

Earth observation data are vital in planning for and dealing with the many hazards from tropical cyclones, such as storm surge, flooding, extreme winds, tornadoes, and lightning. Over the past 50 years, tropical cyclones have killed more than 779,000 people and caused more than $1.4 trillion in economic losses worldwide, according to the WMO.
