The National Weather Service office in Flagstaff produced two very nice documents about 2011. One is a review of top weather events in 2011. It’s a pdf of a Powerpoint slide set. The second is their standard text review of 2011. Here they are:
Top 10 Weather Events in 2011
2011 Year in Review
Both pdfs are worth seeing. The only point I would like to make about the year is that overall it was below average on temperature. Sure, it was dry, but we typically don’t hear about things being colder than average.
La Nina drove the dry weather. La Nina and a cold Pacific Ocean could have contributed to the cooler weather. Also, throughout the year the solar cycle continued to underperform to NASA’s models. The Sun has been very dim. Half a degree of temperature swing may not seem like much. The Arizona Daily Sun didn’t report on the cold year in their 2011 Year in Review: Drought in Flagstaff ends article. Keep in mind that this average temperature included one of Flagstaff’s hottest Augusts on record. By comparison, the global temperatures change by a similar amount during El Nino events. That is typically news.
UAH Global Temperature Update for Dec. 2011
It seems to me that half of a degree merits pointing out. Consider it done.
New weather prediction instrument added!!!
My family gave me an “Admiral Fitzroy’s Storm Glass” for Christmas. You can view it next to my Shark Oil Barometer. It has a similar reported behavior. I think it is still getting acclimated. Wikipedia has Storm Glass page. About.com has a Fitzroy’s Storm Glass page. I will be modifying the barometer webpage to include a Storm Glass section. For now, here is how it should work:
- If the liquid in the glass is clear, the weather will be bright and clear.
- If the liquid is cloudy, the weather will be cloudy as well, perhaps with precipitation.
- If there are small dots in the liquid, humid or foggy weather is expected.
- A cloudy glass with small stars indicates thunderstorms.
- If the liquid has small stars on sunny winter days, then snow is coming.
- If there are large flakes throughout the liquid, it will be overcast in temperate seasons or snowy in the winter.
- If there are crystals at the bottom, this indicates frost.
- If there are threads near the top, it will be windy.
It didn’t seem to change as we had the windy system move through last night. But, we will see what it does in the future. I had to move the barometer out of the window. The storm glass should not be placed in the direct sunlight. I’m not sure where I will leave it.
