Record Global Temperatures for November 2020

by Dr. Mathew Barlow, UML Professor of Climate Science Globally, November 2020 was the warmest November on record: https://climate.copernicus.eu/surface-air-temperature-november-2020 The reds indicate temperatures warmer than the 1981-2010 average and the blues indicate temperatures colder than the 1981-2010 average. (The 1981-2010 period is the current international reference period.) You’ll notice a lot of red. While temperatures […]

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 […]

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 https://storm.uml.edu/~metweb/Blog/?p=578 and https://github.com/mathewbarlow/simple-atmospheric-models. 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 Mathew_Barlow@uml.edu 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 […]

Preparing for Hurricane Season starts now

While Sub Tropical Storm Alberto got the season off to an early start this year, impacting the Gulf Coast this past week, Hurricane Season officially starts tomorrow. The start of the season is usually slow, with more tropical weather occurring from July through October when conditions are more favorable. However, preparations for a landfalling tropical […]
