Atmospheric rivers over eastern US affected by Pacific/North …
Jan 24, 2024 · Atmospheric rivers (ARs) play important roles in various extreme weather events across the US. While AR features in western US have been extensively studied, there remains limited understanding of their variability in the eastern US (EUS).
Response of the upper ocean to northeast Pacific atmospheric …
1 day ago · Atmospheric rivers are important transport vehicles for Earth’s water cycle. Using a high-resolution, eddy-resolving Earth System Model, atmospheric river impacts on the upper ocean are ...
North Atlantic meltwater during Heinrich Stadial 1 drives wetter …
Atmospheric rivers (ARs) bring concentrated rainfall and flooding to the western United States (US) and are hypothesized to have supported sustained hydroclimatic changes in the past.
Atmospheric Rivers | Global Hydrometeorology Resource Center …
Where do atmospheric rivers occur? Atmospheric rivers typically occur in the extratropical North Pacific/Atlantic, southeastern Pacific, and South Atlantic oceans often making landfall on the west coasts of North and South America.
Significant increase of global anomalous moisture uptake ...
Oct 8, 2020 · Here we show an enhanced evapotranspiration rates in association with landfalling atmospheric river events. These anomalous moisture uptake (AMU) locations are identified on a global scale.
Modulation of Atmospheric River Occurrence and Associated Precipitation ...
Dec 27, 2018 · Atmospheric river occurrence in the North Atlantic region differs during distinct low-frequency flow patterns, so-called weather regimes. Blocking anticyclones during weather regimes deviates moisture transport around blocked …

Jun 3, 2023 · The blue shading outlines the maximum and minimum accumulated EAR IVTs averaged in the North Pacific (NP), North Atlantic (NA), South Pacific (SP), and South Atlantic (SA).
Variability and predictability of cold-season North Atlantic ...
Dec 2, 2021 · The sea surface temperature (SST)-forced and internal variability in cold-season (December–March) atmospheric river (AR) occurrence frequency during 1951–2010 over the North Atlantic (NA) basin are examined using a 30-member ensemble of high-resolution atmospheric simulations.
A cluster analysis of cold-season atmospheric river tracks over …
May 20, 2022 · Using reanalysis and high-resolution ensemble simulations, we characterize cold season (December−March) North Atlantic (NA) atmospheric river (AR) tracks by grouping them into four distinct clusters; then for each cluster, we link the year-to-year variations in track count to large-scale climate variability and examine the climatological ...
