Western disturbances and climate variability: a review of recent developments Open
Western disturbances (WDs) are synoptic-scale weather systems embedded within the subtropical westerly jet. Manifesting as upper-level troughs often associated with a lower-tropospheric low over western or northern India, they share some d…

Impact of atmospheric rivers on Arctic sea ice variations Open
Arctic sea ice has been declining rapidly in recent decades. We investigate how the poleward transport of moisture and heat from lower latitudes through atmospheric rivers (ARs) influences Arctic sea ice variations. We use hourly ERA5 (fif…
Performance of New Near-Real-Time PERSIANN Product (PDIR-Now) for Atmospheric River Events over the Russian River Basin, California Open
Most heavy precipitation events and extreme flooding over the U.S. Pacific coast can be linked to prevalent atmospheric river (AR) conditions. Thus, reliable quantitative precipitation estimation with a rich spatiotemporal resolution is vi…

Atmospheric River Reconnaissance 2021: A Review Open
Atmospheric River Reconnaissance (AR Recon) is a targeted campaign that complements other sources of observational data, forming part of a diverse observing system. AR Recon 2021 operated for ten weeks from January 13 to March 22, with 29.…
Impact of Atmospheric Rivers on Arctic Sea Ice Variations Open

Improving confidence in model-based Probable Maximum Precipitation : Assessing sources of model uncertainty in storm reconstruction and maximization  Open
We present an analysis of uncertainty in model-based Probable Maximum Precipitation (PMP) estimates. The focus of the study is on model-based PMP derived from WRF (Weather Research and Forecasting) model reconstructions of severe historica…
Complementary observations aid identification of the mountain rain-snow transition elevation Open
The elevation of the mountain rain-snow transition is critical for short-term hazard forecasting and longer-term water supply considerations. Despite the transition’s importance, direct in-situ observations are rare. Here we present two ne…
Temporal changes in rainfall intensity–duration thresholds for post-wildfire flash floods in southern California Open
Rainfall intensity–duration (ID) thresholds are commonly used to assess flash flood potential downstream of burned watersheds. High-intensity and/or long-duration rainfall is required to generate flash floods as landscapes recover from fir…
Complementary observations aid identification of the mountain rain-snow transition elevation Open
If data have a time stamp, all data are in UTC Includes: precipitation gauge [meters] data from California Data Exchange (CDEC) SNOTEL data (soil moisture [%], snow water equivalent [meters]) snow depth [meters] data from snow pillow sites…

Illustrating Ensemble Predictability across Scales Associated with the 13–15 February 2019 Atmospheric River Event Open
The “Valentine’s Day” atmospheric river (AR) event that affected a majority of California during 13–15 February 2019 ranked as an AR3 (Ralph et al. 2019) along most of the California coast and reached AR4 intensity in Southern California. …

A Climatology of Narrow Cold‐Frontal Rainbands in Southern California Open
Narrow cold‐frontal rainbands (NCFRs) produce short‐duration, high‐intensity precipitation associated with flash flooding and debris flows in Southern California, including the extremely destructive 2018 Montecito event. This manuscript pr…
When It Rains It’s Poorly Observed: Data Gaps within Atmospheric Rivers Aimed at the West Coast Open
andfalling atmospheric rivers (ARs) over the northeastern Pacific are responsible for up to 50% of the annual precipitation over the western United States.As such, these elongated corridors that transport water vapor from the subtropics an…

Representation of Dropsonde‐Observed Atmospheric River Conditions in Reanalyses Open
Atmospheric rivers (ARs) are the primary mechanism for mid‐latitude water vapor transport, and are identified by a key variable, integrated water vapor transport (IVT). The ability of atmospheric reanalyses in providing a ground‐truth data…

Data Gaps within Atmospheric Rivers over the Northeastern Pacific Open
Conventional observations of atmospheric rivers (ARs) over the northeastern Pacific Ocean are sparse. Satellite radiances are affected by the presence of clouds and heavy precipitation, which impact their distribution in the lower atmosphe…

West Coast Forecast Challenges and Development of Atmospheric River Reconnaissance Open
Water management and flood control are major challenges in the western United States. They are heavily influenced by atmospheric river (AR) storms that produce both beneficial water supply and hazards; for example, 84% of all flood damages…
Quantifying the Spatial Variability of a Snowstorm Using Differential Airborne Lidar Open
California depends on snow accumulation in the Sierra Nevada for its water supply. Snowfall is measured by a combination of snow pillows, snow courses, and rain gauges. However, the paucity of locations of these measurements, particularly …
