On the simulation of the quasi-biennial oscillation in the Community...
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...- publication PDF

Poleward excursions by the Himalayan subtropical jet over the past four centuries
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...- publication PDF

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

Comparison of filtering methods for the modeling and retrospective...
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...- publication PDF

Energy modulations of magnetospheric ions induced by foreshock...
Although foreshock transients can generate strong magnetospheric Pc5 ultralow-frequency (ULF) waves, whether they can modulate the energy of magnetospheric ions is still poorly...- publication PDF
