A new probabilistic tornado detection algorithm was developed to potentially replace the operational tornado detection algorithm (TDA) for the WSR-88D radar network. The tornado...

The thermal component of oceanic eddy available potential energy (EPE) generation due to air-sea interaction is proportional to the product of anomalous sea surface temperature...

This paper presents observations of deep convection characteristics in the tropics and subtropics that have been classified into four categories: tropical cyclone, oceanic,...

Global tropical cyclone (TC) activity is simulated by the Geophysical Fluid Dynamics Laboratory (GFDL) Climate Model, version 2.5 (CM2.5), which is a fully coupled global...

Explicit attributes of convective storms within convection-allowing model (CAM) forecasts are routinely used as surrogates for convective weather hazards. The ability of 3- and...

The development of tropical cloud clusters (TCCs) to tropical cyclones (TCs) is the process of TC formation. This study identifies five main environmental transitions for the...

Peroxyacetyl nitrate (PAN) plays a fundamental role in the global ozone budget and is the primary reservoir of tropospheric reactive nitrogen over much of the globe. However,...

Due to their importance for the radiation budget, liquid-containing clouds are a key component of the Arctic climate system. Depending on season, they can cool or warm the near-...

The assessment of forest-based climate change mitigation strategies relies on computationally intensive scenario analyses, particularly when dynamic vegetation models are...

This study predicts summer (June-September) fire burned area across the western United States (U.S.) from 1984 to 2020 using ensembles of statistical models trained with pre-...

The structure and amplitude of the radiative contributions of the annual cycles in ozone and water vapour to the prominent annual cycle in temperatures in the tropical...

An air-water coupled model is developed to investigate wind-wave generation processes at low wind speed where the surface wind stress is about 0.089 dyn cm⁻² and the...

This technical note presents a numerical technique for calculating isentropic trajectories, and the objective analysis of trajectoryderived meteorological parameters. A brief...

For 15 years, the Undergraduate Leadership Workshop (ULW) has connected undergraduate students with scientists, engineers, educators, and leadership at the National Center for...

Scientific investigation is supposed to be objective and strictly logical, but this is not always the case: the process that leads to a good conclusion can be messy. This...

The concentration, size, and composition of non-refractory submicron aerosol (NR-PM₁) was measured over Mexico City and central Mexico with a High-Resolution Time-of-Flight...

The Parallel Ocean Program (POP), the ocean model component of the Community Earth System Model (CESM), is widely used in climate research. Most current work in CESM-POP focuses...

Studying convection, which is one of the least understood physical mechanisms in the tropical atmosphere, is very important for weather and climate predictions of extreme events...

This study addresses a long-standing scientific puzzle regarding ionospheric F-2 region dynamics. Incoherent scatter radar observations of F-2 region plasma drifts showed a...

The “extended solar cycle” indicates that there are two deeply seated toroidal magnetic field bands in each hemisphere. Both bands migrate equatorward as a sunspot...
