Accurate and real-time estimation of surface precipitation is crucial for decision-making during severe weather events and for water resource management. Polarimetric weather...

The study presents an overview of the El Nino/Southern Oscillation (ENSO) phenomenon and Pacific Decadal Variability (PDV) simulated in a multi-century pre-industrial control...

Atmospheric science is male dominated and few students of color matriculate into the field, a trend dating back at least 50 years. UCAR/NCAR Equity and Inclusion (referred to as...

Following the Hunga Tonga-Hunga Ha'apai (HTHH) eruption in January 2022, stratospheric ozone depletion was observed at Southern Hemisphere mid-latitudes and over Antarctica...

An open question in cloud physics is how rain forms in warm cumulus as rapidly as it is sometimes observed. In particular, the growth of cloud droplets across the size gap from...

Accurate prediction of sea surface temperatures (SSTs) in the tropical North Atlantic on multiyear timescales is of paramount importance due to its notable impact on tropical...

The role of time-dependent freezing of ice nucleating particles (INPs) is evaluated with the "Aerosol-Cloud" (AC) model in 1) deep convection observed over Oklahoma during the...

The effects of anthropogenic warming on the hydroclimate of California are becoming more pronounced with the increased frequency of multi-year droughts and flooding. As a past...

Heavy ion signatures of coronal mass ejections (CMEs) indicate that rapid and strong heating takes place during the eruption and early stages of propagation. However, the nature...

A novel aerosol activation scheme was developed and implemented into the WRF Thompson-Eidhammer Aerosol-Aware microphysical module. While in most of the numerical weather...

Common disaster-phase models provide a useful heuristic for understanding how disasters evolve, but they do not adequately characterize the transitions between phases, such as...

Precipitation changes in full response to CO2 increase are widely studied but confidence in future projections remains low. Mechanistic understanding of the direct radiative...

In this two-part paper the biases of polarimetric variables from simultaneous horizontally and vertically transmitted (SHV) data are investigated. Here, in Part I, a radar-...

The Geophysical Fluid Dynamics Laboratory (GFDL)'s System for High‐resolution prediction on Earth‐to‐Local Domains (SHiELD) model typically uses the National...

Single-forcing large ensembles are a relatively new tool for quantifying the contributions of different an-thropogenic and natural forcings to the historical and future...

Regional- and continental-scale hydrologic models are increasingly important forecasting tools, yet they rely on highly variable channel parameters (e.g. width, depth, hydraulic...

Measurements of carbon monoxide (CO) made as part of three aircraft experiments during the summer of 2004 over North America have been used for the continued validation of the...

A stochastic horizontal subgrid-scale mixing scheme is evaluated in ensemble simulations of a tropical oceanic deep convection case using a horizontal grid spacing (Delta h) of...

Through interactions between the modes of "waves" and "vortices", stably stratified turbulence exhibits characteristic features both in 2D and 3D. Using DNS of the Navier-Stokes...
