Frequency redistribution function for the polarized two-term atom
We present a generalized frequency redistribution function for the polarized two-term atom in an arbitrary magnetic field. This result is derived within a new formulation of the...- publication PDF

Severe convective storms in limited instability organized by pattern and distribution
Severe convection occurring in high-shear, low-CAPE (HSLC) environments is a common cool-season threat in the southeastern United States. Previous studies of HSLC convection...- publication PDF

On the asymptotic joint distribution of sample space-time covariance estimators
We study the asymptotic joint distribution of sample space–time covariance estimators of strictly stationary random fields. We do this without any marginal or joint...- publication PDF

Investigation of cirrus cloud properties in the tropical tropopause layer...
Tropical-tropopause-layer cirrus clouds and their radiative effects represent a major uncertainty in the evaluation of Earth’s energy budget. High-altitude aircraft offer an...- publication PDF
