Mammatus Clouds in Michigan

Amazing video capture of mammatus clouds combined with some dramatic and vibrant sunset colors over Michigan’s Upper Peninsula: http://www.latimes.com/news/science/sciencenow/la-sci-sn-orange-bubble-clouds-video-20130726,0,4837916.story.

The article (from The Los Angeles Times) describes mammatus clouds as “upside-down clouds” that appear, round, smooth, and bubbly. I hope to see these with my own eye someday! Mammatus can be an indicator of severe weather nearby, and aviation activity is warned to avoid flying too close when these fascinating shapes are present in the sky.

NWS San Diego Visit

Yesterday, Ivory Small (Science and Operations Officer) and the rest of the crew at the National Weather Service WFO in San Diego were kind enough to host a few of us for the day. Kayla Jordan (our summer intern), Jim Purpura (former director at the San Diego WFO), and myself discussed the Elsinore Convergence Zone with Ivory, who has documented several cases and is essentially an expert. There is not a tremendous amount of research on the convergence zone. Severe weather is very real in California, and I believe the public’s lack of awareness for it is a serious problem in our state. As a meteorologist, I want to help improve that.

Our goal in visiting the office was to finalize our research topics for an upcoming joint project, and I’d say it was a very successful day. Thanks again for welcoming us in, NWS San Diego. And an extra special thanks to Ivory for taking the time to meet with us!

Some pictures from the trip…
