Spontaneous clumping of tropical clouds

by | July 23, 2015 | 1 Comment

If you take a look at nearly any satellite image of clouds in the tropics (for example, the GOES west geostationary satellite image from a few days ago), you’ll notice that convective clouds (the tall thunderstorm clouds associated with strong circulations) tend to be organized into clusters. This clustering ranges from features such as squall […]

First Extremes Workshop: Mission Accomplished

by | May 8, 2015

Our workshop, Extreme Weather and Climate: Hazards, Impacts, Actions, happened yesterday. For me, it went by in a blur. A little like attending your own wedding, you’re so caught up in it that you can’t quite tell how you’d react to it if you weren’t. But maybe that feeling of being overwhelmed was partly due to the content. […]

This coming Wednesday, May 6, we will have our first science workshop for the Extremes Initiative. We’re calling it Extreme Weather and Climate: Hazards, Impacts, Actions, and it will be an intense day of science talks. We’ve left time in the program for discussion as well. So although the crowd looks like it will be […]

Clouds, circulation and climate sensitivity

by | April 8, 2015

I’m a co-author on a paper that appeared last week in Nature Geoscience entitled “Clouds, Circulation and Climate Sensitivity”. This paper describes a “Grand Challenge”, one of several activities with that label, all begun in the last couple of years under the World Climate Research Programme (WCRP). For about another three weeks, the paper is freely […]

Kickoff event video now online

On February 23 we formally launched the Initiative with an event in the Columbia World Leaders Forum series. After some introductory remarks by Executive VP for Research Michael Purdy, and then some by me, the main attraction was a panel discussion. The panel covered lessons learned in New York City from Sandy about how to prepare for […]

Super Typhoon Maysak

  Right now in New York City it is 48 F, still cold (at least to me, since I’ve only lived in Taipei and Miami), but we know spring is finally stepping in. In the meantime, for people in another part of the world, the western north Pacific, nature has already given them a sign […]

This is the new blog for the Columbia Initiative on Extreme Weather and Climate. We hope to feature semi-regular posts by a team of writers that will include some of our young scientists, postdoctoral research associates in particular, as well as myself and other senior people. We will comment on extreme weather events, summarize research […]
