New Research From NASA Identifies causes of sea-level rise since 1900

Sea-level rise is a major issue stemming from the bigger picture of Climate Change, and one that will have great impacts at the local and regional levels. Globally, it is estimated that 634 million people are at immediate risk due to sea-level rise, with the United States alone seeing around 40% of the population living in coastal areas.

Tropical Storm Isaias

Tropical Storm Isaias is near the Carolina coastline this afternoon, but struggling to maintain its intensity. As of 2pm Monday, Tropical Storm Isaias was centered about 115 miles south of Charleston, South Carolina, moving toward the north at 13 mph. Maximum sustained winds remain near 70 mph. A Hurricane Warning is in effect from South […]

Tropical Storm Fay

by David Coe, EEAS Ph.D Student New England is bracing for impact from Tropical Storm Fay this weekend that could bring torrential rains, heavy winds, and strong embedded storms to the region. Although uncommon, New England does see its fair share of Tropical Cyclones, but mainly as post-tropical storms. Tropical Storm Fay being the 4th […]

Gallery of Atmospheric Dynamics Animations

by Mathew Barlow, EEAS Professor of Climate Science This post includes twenty short animations from our undergraduate two-course sequence in atmospheric dynamics.  Topics covered include vorticity, waves, and instability. The code used for these animations can be found through and 1.  Winds and rotors for an idealized vortex Embedding rotors (‘+’) in the flow allows […]

Simple Atmospheric Models: Resources

by Mathew Barlow, EEAS Professor of Climate Science This post gives links to freely-available code for simple models of the atmosphere (and ocean). If you know of anything I’ve missed, please email me at and I will add it here. Many thanks to Daniela Domeisen, Geoff Vallis, Malte Stuecker, Nathaneal Wong, Milan Klöwer, and […]

What do blocks and jet streaks have in common?

by Mathew Barlow, Professor of Climate Science Blocks and jet streaks appear to be fairly different phenomena. However, in a very idealized sense, they can be thought of two versions of the same configuration: two oppositely-rotating vortices embedded in a westerly flow. Two opposite vortices, no background flow Two counter-rotating vortices that are nearby will […]
