5 天之前 · The Atmospheric Rivers Version 1 (AR V1) is a historical record of ARs and related fields based on the ERA5 Reanalysis. The data is regional in coverage (Western U.S.), high resolution in both space (~31 km) and time (6 h), and covers a long period of record (1940-present). It uses the AR scale to broadly characterizes the strength of ARs using categorical rankings from 1-5 based on the peak ...

1 天前 · It's a type of atmospheric river that forms a long, narrow tract in the Earth’s atmosphere. This jet stream gathers moisture from the tropics near the equator and sweeps it toward the poles.

大气层河流（atmospheric river）是位于对流层下层的，天气尺度的狭长水汽输送路径。 大气层河流可见于热带至中纬度地区的洋面，可在全年出现，其出现时通常伴随有海洋性气旋、锋面活动和低空急流。

2024年1月25日 · Atmospheric rivers are long, narrow plumes of moisture transported by winds from the tropics. When they move over land, their heavy precipitation can trigger flooding and landslides. But they...

Atmospheric rivers are long, concentrated regions in the atmosphere that transport moist air from the tropics to higher latitudes. The moist air, combined with high wind speeds, produce heavy rain and snow upon landfall, especially over mountainous terrain.

2023年3月9日 · An atmospheric river is a plume of moisture that helps carry saturated air from the tropics to higher latitudes, delivering unrelenting rain or snow. Think of it as a fire hose that aims at –...
