Studies of a rapid change detector using CYGNSS level-2 wind speed products
This work further investigates the use of ocean wind speed retrievals from NASA's Cyclone Global Navigation Satellite System (CYGNSS) mission that are closely spaced in space...- publication PDF

Upscale versus "up-amplitude" growth of forecast-error spectra
Atmospheric predictability is measured by the average difference (or "error") within an ensemble of forecasts starting from slightly different initial conditions. The spatial...- publication PDF

Tropical cyclone formation within strong northeasterly environments in the...
In the South China Sea (SCS), 17% of tropical cyclones (TCs) formed in the late season (November-January) were associated with a strong northeasterly monsoon. This study...- publication PDF

The emergence of shallow easterly jets within QBO westerlies
A configuration of an idealized general circulation model has been obtained in which a deep, stratospheric, equatorial, westerly jet is established that is spontaneously and...- publication PDF

Global observing needs in the deep ocean
The deep ocean below 200 m water depth is the least observed, but largest habitat on our planet by volume and area. Over 150 years of exploration has revealed that this dynamic...- publication PDF

Solar cycle variations of thermospheric composition at the solstices
We examine the solar cycle variability of thermospheric composition (O/N2) at the solstices. Our observational and modeling studies show that the summer-to-winter latitudinal...- publication PDF

Simulating properties of "seasonal" variability in solar activity and space...
Solar short-term, quasi-annual variability within a decadal sunspot-cycle has recently been observed to strongly correlate with major class solar flares, resulting into quasi-...- publication PDF
