An interesting 24 hours here in SoCal. This story about the “missile” is fascinating. If you haven’t seen the video, here’s the report from a San Diego CBS affiliate (they do a lot of cross-work/outsourcing to their sister station in LA):
So you be the judge. Is that a missile? At first, I was flat sold on it. And to some extent I’m still skeptical it isn’t. What appears to be a rapid movement of whatever it is has me still curious. Time for the obligatory: BUT. But…sunset can do some mighty weird tricks to your eyes. I’ve seen high level clouds at sunset that were at least 100 miles offshore before. And as explained in this blog entry (based on a similar event from several months ago), it’s entirely possible, if not likely, that what was witnessed off the coast of LA was not a missile, but a contrail from a commercial jet. In fact, the author of that blog has pinned down what flight they suspect it was. The government subscribes to that theory…for what it’s worth I suppose. The chopper pilot who caught whatever it was seems to be convinced otherwise. I’m going to cautiously side with the government’s explanation for now. Like I said, weird optical tricks can be played on you at sunset, and the theory about the flight, the timing, and the flight path makes sense. Yesterday was a decent day for contrails as well, so that explanation doesn’t come off as a cop out…it seems rather legitimate. We’ll see what we find out down the line.
Indonesia continues to be active. Mt. Merapi is so much of an issue right now that President Obama is having to cut short his visit to the country because of concerns about ash from the volcano. Ash and aircraft do not mix at all, so this is probably a prudent move. The image to the left is damage from Merapi as seen by James Reynolds, a videographer of all things natural disaster. Like the volcano in Iceland earlier this year, there is a webcam set up near the mountain. Unfortunately this seems to be very hot and cold, so you may want to bookmark it and periodically check it. According to the Eruptions volcano blog, the estimate is that Merapi has had a VEI (Volcano Explosivity Index) of between 3 and 4 so far. Just to put this in perspective, Mt. Redoubt in Alaska, which erupted in the spring of 2009 was around a VEI3. Our Icelandic volcano this past year (Eyjafjallajökull) was probably similar, if not a little less than Redoubt. So there isn’t anything substantially noteworthy about this from a large scale perspective at this point. For Merapi, this is a pretty typical eruption for it, where historically they’ve had VEI3-4 eruptions.
Lastly, here’s some Associate Press footage of the ash cloud from Merapi. Certainly an impressive scene:

Snow fell in Denver finally today, marking the first for them this winter season as well. Those of you snow hounds will enjoy some of the videos in that link, shot by storm chaser Tony Laubach.
A weather enthusiast in Seattle has been analyzing the satisfaction or misery of the summer and winter seasons by doing a statistical analysis. Well, it turns out the summer of 2010 was the 6th worst summer in Seattle since 1948. Summers and autumns in Seattle can be phenomenal, so this is ashame, especially since we’re in a La Nina, which climatologically favors greater than normal precipitation in the Northwest in winter.
Additional work is underway to try and secure New Orleans and surrounding areas from storm surge impacts during a hurricane.
Lastly, a fascinating blog entry…warning: long read about the scientific method and its applications in the current climate science debate. The author is a sociologist of science (awesome title), which basically means he’s studying the philosophy of science. It’s well worth a read (in fact, I am going to re-read it), as the argument about adhering to the principles of the scientific method has been a point of contention, especially since Climategate.
