North or south? How the position of sea surface temperature anomalies in the North Pacific can influence the stratospheric polar vortex in the Arctic

Previous studies have found that phase changes in the sea surface temperature (SST) of the North Pacific can modulate the variations in the stratospheric polar vortex (SPV) in the Arctic, which is a circulation of winds high up in the stratosphere with strong impacts on regional weather patterns.

Taking greenhouse gas analysis on the road, er, rails

Since 2014, the University of Utah has maintained research-grade suites of air quality instruments installed on light rail trains. These mobile sensors cover the same area as 30 stationary sensors, providing the Salt Lake Valley with a highly cost-effective way to monitor its greenhouse emissions and fill in gaps in emissions estimates.

Columbia Researchers Provide New Evidence on the Reliability of Climate Modeling

Observational data of equatorial circulation pattern confirms that the pattern is weakening, a development with important consequences for future rainfall in the subtropics.
