When our Sun was young it rotated much more rapidly than now. Observations of young, rapidly rotating stars indicate that many possess substantial magnetic activity and strong...

We present an asteroseismic study of the solar-like stars KIC 11395018, KIC 10273246, KIC 10920273, KIC 10339342, and KIC 11234888 using short-cadence time series of more than...

In this study, we estimate a time series of geocenter anomalies from a combination of data from the Gravity Recovery and Climate Experiment (GRACE) satellite mission and the...

Starting from three Eulerian second-order nonlinear advection schemes for semi-staggered Arakawa grids B/E, advection schemes of fourth order of formal accuracy were developed....

Changes in the thermosphere-ionosphere system caused by high-speed streams in the solar wind, and the co-rotating interaction regions they engender, are studied using a...

The East Asian summer monsoon (EASM) circulation and summer rainfall over East China have experienced large decadal changes during the latter half of the 20th century. To...

In late October and early November of 2003, the Sun unleashed a powerful series of events known as the Halloween storms. The coronal mass ejections launched by the Sun produced...

The roughness of the land surface (z(0)) is a key property, exerting significant influence on the amount of near-surface turbulent activity and consequently the turbulent...

This bottom-up modeling study, supported by new population census 2011 data, simulates ozone (O₃) and fine particulate matter (PM₂.₠) exposure on local to regional scales....

The spectral line profile of the atomic oxygen (OD2)-D-1- P-3(2) transition near 6300 A in the airglow has been used for more than 50 years to extract neutral wind and...

Ozone is the third most important anthropogenic greenhouse gas after carbon dioxide and methane but has a larger uncertainty in its radiative forcing, in part because of...

This report discusses the results of a series of wind tunnel and field tests performed in support of a program to develop a balloon inflation and launch shelter. The study...

Geoengineering with stratospheric sulfate aerosols has been proposed as a means of temporarily cooling the planet, alleviating some of the side effects of anthropogenic CO₂...

Tropical cyclone numbers can vary from week to week within a hurricane season. Recent studies suggest that convectively coupled Kelvin waves can be partly responsible for such...

This technical note provides an outline of the numerical scheme and worldwide contour maps of the electric potential, ionospheric current vectors, and the equivalent ionospheric...

We investigate the accuracy to which we can retrieve the solar photospheric magnetic field vector using the Helioseismic and Magnetic Imager (HMI) that will fly onboard of the...

The interpretation of emission lines formed in large astrophysical plasmas such as the solar atmosphere faces many challenges. Relatively simple line-ratio estimates of physical...

We present the global characteristics of rotating convective updrafts in the 2021 version of GFDL's eXperimental System for High-resolution prediction on Earth-to-Local Domains...

Although the tropopause is a well-established concept, its definition and physical properties remain an active research topic. In the tropics, both the World Meteorological...

Boundary layer turbulent processes affect tropical cyclone (TC) structure and intensity change. However, uncertainties in the parameterization of the planetary boundary layer...
