Changing global fire regimes including extended fire seasons due to climate change may increase the co-occurrence of high-impact fires that overwhelm national fire suppression...

This study compares the global distribution of 20th century SST and marine air temperature trends from a wide variety of data sets including un-interpolated archives as well as...

A method to simulate characteristics of wind speed in the boundary layer of tropical cyclones in an idealized manner is developed and evaluated. The method can be used in a...

Multiyear turbulence measurements from oceanographic moorings in equatorial Atlantic and Pacific cold tongues reveal similarities in deep cycle turbulence (DCT) beneath the...

The column number density ratio of atomic oxygen to molecular nitrogen (O/N₂ ratio) provided by the Global Ultraviolet Imager (GUVI) onboard the Thermosphere, Ionosphere,...

The Beijing Climate Center Earth System Model version 1 (BCC-ESM1) is the first version of a fully coupled Earth system model with interactive atmospheric chemistry and aerosols...

Air pollution experienced by expanding urban areas is responsible for serious health effects and death for millions of people every year. Trash burning is a common disposal...

Tropical cyclones (TCs) are a hazard to life and property and a prominent element of the global climate system; therefore, understanding and predicting TC location, intensity,...

The sea level contribution of the Antarctic ice sheet constitutes a large uncertainty in future sea level projections. Here we apply a linear response theory approach to 16...

In contrast to the modern-day climate, North Pacific deep water formation and a Pacific meridional overturning circulation (PMOC) may have been active during past climate...

Under-catch errors in precipitation gauge records can be as large as 50-100% during the cold season at high latitudes. To quantify the impacts of these errors on...

Risk communication may accentuate or alleviate the vulnerability of people who have particular difficulties responding to the threat of hazards such as hurricanes. The process...

The project Land-Use and Climate, Identification of Robust Impacts (LUCID) was conceived to address the robustness of biogeophysical impacts of historical land use--land cover...

This report, from the Scientific Computing Division (SCD), highlights the latest visualization tools to the atmospheric and oceanographic research communities served by NCAR....

On 15 May 1999, a storm intercept team from the University of Oklahoma collected high-resolution, W-band Doppler radar data in a tornado near Stockton, Kansas. Thirty-five...

We report a new modeling capability that self-consistently couples physics-based magnetospheric electron precipitation with its impact on the ionosphere. Specifically, the ring...

The Year of Tropical Convection (YOTC) project recognizes that major improvements are needed in how the tropics are represented in climate models. Tropical convection is...

We have diagnosed the lifetimes of long-lived source gases emitted at the surface and removed in the stratosphere using six three-dimensional chemistry-climate models and a two-...

The criteria and assumptions that were used to derive the steady-state tropical cyclone intensity and structure theory of Emanuel and Rotunno are assessed using three-...

This paper studies the effects of climate change under future A1B scenario and land use change on surface ozone (O₃) in the greater Houston, Texas, area. We applied the Weather...
