In this fourth volume of a four volume series depicting the upper air climatology of the Southern Hemisphere, a cross sections of mean statistics for heights, temperatures, and...

The International Surface Pressure Databank (ISPD) is the world's largest collection of global surface and sea-level pressure observations. It was developed by extracting...

Organic aerosols (OA) represent a significant fraction of total submicron particulate matter (PM1) concentrations globally, including densely populated megacities such as Seoul....

Is education the best contraceptive? Using the multistate human capital projection model, our analysis shows that the projected changes in India population vary depending on...

South Korea routinely experiences poor air quality with ozone and small particles exceeding air quality standards. To build a better understanding of this problem, in 2016, the...

Stochastically generated streamflow time series are used for various water management and hazard estimation applications. They provide realizations of plausible but as yet...

A stochastically perturbed parameterization (SPP) approach that spatially and temporally perturbs parameters and variables in the Mellor-Yamada-Nakanishi-Niino planetary...

The polar region has been one of the fastest warming places on Earth in response to greenhouse gas (GHG) forcing. Two distinct processes contribute to the observed warming...

There is a clear distinction between simple laminar and complex turbulent fluids; however, in some cases, as for the nocturnal planetary boundary layer, a stable and well-...

Local finite-amplitude wave activity (LWA) measures the waviness of the local flow. In this work we relate the anticyclonic part of LWA, AWA (anticyclonic wave activity), to...

Each summer since 1966 the NCAR Computing Facility has conducted a Summer Fellowship Program to provide on-the-job training in computer programming and research for graduate...

Long-term and continuous observations of mesospheric-lower thermospheric winds are rare, but they are important to investigate climatological changes at these altitudes on...

The principal rainband in tropical cyclones is currently depicted as a solitary and continuous precipitation region. However, the airborne radar observations of the principal...

Medium-scale ionospheric ionization structures are a persistent global feature of the Earth's ionosphere. Constellation Observing System for Meteorology, Ionosphere, and Climate...

Fluid circulation in the Earth's crust plays an essential role in surface, near surface, and deep crustal processes. Flow pathways are driven by hydraulic gradients but...

Wildfires are by far the largest contributor to global biomass burning and constitute a large global source of atmospheric traces gases and aerosols. Such emissions have a...

This study summarizes recent improvements in the development of bulk scattering/absorption models at solar wavelengths. The approach combines microphysical measurements from...

A new electrification and discharge model was developed based on a two‐moment bin microphysical scheme coupled with the Weather Research and Forecasting (WRF) model. Based on...

Measurements of ice number concentration in clouds are important but still pose problems. The pattern of ice development in stratiform mixed-phase clouds (SMCs) offers an...

Extreme precipitation is among the most destructive natural disasters. Simulating changes in regional extreme precipitation remains challenging, partially limited by climate...
