The subpolar North Atlantic (SPNA) is a region with prominent decadal variability that has experienced remarkable warming and cooling trends in the last few decades. These...

Mediterranean hurricanes (Medicanes) are intense cyclones that acquire tropical characteristics, associated with extreme winds and rainfall, thus posing a serious natural hazard...

Hinode is Japan's third solar mission following Hinotori (1981–1982) and Yohkoh (1991–2001): it was launched on 2006 September 22 and is in operation currently. Hinode...

Anthropogenically-induced changes in the global meridional overturning circulation since the 1950s have led the upper overturning cell in the Southern Ocean to expand and...

Atmospheric models used for weather prediction and future climate projections rely on landmodels to calculate surface boundary conditions. Observations of near-surface states...

Recommendations for instruments and capabilities needed to advance the study of atmospheric convection and turbulence are presented.

Polar stereographic maps and meridional cross-sections of selected circulation statistics for the extratropical regions from 1000 to 100 mb (20-90��N) of the Northern...

Leveraging the unique perspective enabled by Global‐scale Observations of the Limb and Disk, we examined the characteristics of equinox transitions in the thermospheric...

Recent extreme fire seasons in California have prompted utilities such as Pacific Gas and Electric to pre-emptively de-energize portions of the electrical grid during periods of...

The performance of two-way nesting for large eddy simulation (LES) of PBL turbulence is investigated using the Weather Research and Forecasting model framework. A pair of LES-...

The atmospheric lunar tide is one known source of ionospheric variability. The subject received renewed attention as recent studies found a link between stratospheric sudden...

We assess model capability in simulating thermospheric response to recurrent geomagnetic forcing driven by modulations in the solar wind speed and the interplanetary magnetic...

The two dominant drivers of the global mean sea level (GMSL) variability at interannual timescales are steric changes due to changes in ocean heat content and barystatic changes...

The quasi-biennial oscillation (QBO) of the tropical zonal mean wind is a prominent feature of the tropical stratosphere. The easterly and westerly wind regimes alternate with a...

Since the 1980s, the subtropical jet stream has generally moved poleward, but its behavior varies by region and season. Here we examine the interannual variability and trends in...

Laboratory measurements of the Electrochemical Concentration Cell (ECC) ozone sonde cell current using ozone free air as well as defined amounts of ozone reveal that background...

By analyzing data from satellite measurements, a reanalysis, and a chemistry-climate model, we found clear zonally uniform tidal signals in the tropical stratosphere,...

A variety of filtering methods enable the recursive estimation of system state variables and inference of model parameters. These methods have found application in a range of...

We present a multi-instrumental study of ionospheric irregularities of different scales (from tens of centimeters to few kilometers) observed over the Central and East Siberia,...

In this study w e explored why the different initial tropical cyclone structures can result in different steady-state maximum intensities in model simulations with the same...
