The striated solar photosphere observed at 0". 03 resolution
Striated granular edges observed in the solar photosphere represent one of the smallest-scale phenomena on the Sun. They arise from the interaction of strongly coupled...- publication PDF

Impact of anthropogenic climate change on United States major hurricane...
Although anthropogenic climate change has contributed to warmer ocean temperatures that are seemingly more favorable for Atlantic hurricane development, no major hurricanes made...- publication PDF

Simulations of the response of the mesospheric circulation and temperature...
The loss of ozone that has occurred in the Antarctic lower stratosphere during each spring since 1980 has led to a decrease in the lower stratospheric temperature that persists...- publication PDF
