Air parcel trajectory dispersion near the tropical tropopause
Dispersion of backward air parcel trajectories that are initially tightly grouped near the tropical tropopause is examined using three ensemble approaches: "RANWIND," in which...- publication PDF

Stratospheric ozone depletion: An unlikely driver of the regional trends in...
It has been suggested that recent regional trends in Antarctic sea ice might have been caused by the formation of the ozone hole in the late twentieth century. Here we explore...- publication PDF

Why the western Pacific subtropical high has extended westward since the late 1970s
he western Pacific subtropical high (WPSH) is closely related to Asian climate. Previous examination of changes in the WPSH found a westward extension since the late 1970s,...- publication PDF
