For as long as we have had weather records (extending back into the 1800s), lobes of cold air rotating generally from west to east around the polar vortex sometimes extend down into the U.S. causing wild winter weather and general unpleasantness. We used to call this pro...
Obtaining high-rate data from the mesosphere-lower thermosphere region is a chal- lenge, and continuous ground observations of the mesospheric wind and temperature in the vicinity of the stratospheric polar vortex edge are still rare. Furthermore, sudden strato- spheric warming (SSW) manifestations...
The results show that there exists a strong correlation between the accuracy of the stratospheric vortex and AO prediction. These studies demonstrated the importance of polar vortex intensity prediction, but they did not clearly predict the day-to-day variation of the polar vortex, and the polar ...
The membranes were diluted to the chosen concentration with simplified ATPase assay buffer and warmed to 37 °C. The NBD amphiphiles were added from stocks in DMSO (final DMSO 1% v/v) by squirting the required volume into the membrane solution under gentle vortex. Fluorescence intensity was meas...
