In one of the most comprehensive studies on trends in local severe weather patterns to date, an international team of researchers found that the frequency of hail storms, thunderstorms and high wind events has decreased by nearly 50 percent on average throughout China since 1960. "The frequency of thunderstorms and high winds decreased gradually over the time period we studied, but not hail," said Qinghong Zhang. "This is something we don't fully understand at this point but plan to investigate more."To their credit, the Chinese researchers are real scientists, considering a variety of causes. USA "scientists" are blind bigots, locked into worshipping Gaia. (For instance.) Pollution makes sense as the major cause. More particles means more seeding, more steady precipitation AND more even distribution of charge. Less chance to build up heavy clouds and heavy charge differences, thus less severe thunderstorms. More particles also means more even distribution of temperature over both space and time, thus flatter thermal gradients, thus less push and pull for wind. = = = = = Here's a chart of tornados and wind over a similar period in USA, from NOAA. I'd like to find a chart of US particulate pollution from a similar period, focusing on tornado territory. Closest I can find for now is this from AEI. The lower line is national. Pollution has decreased steadily nationwide since 1920. Nationally the EPA didn't change the curve much, which is typical of all Federal "solutions". The purpose of a "solution" is to preserve the problem and increase bureaucratic workforce. Parkinson. However: I know from living in Oklahoma that pollution decreased strongly during the 1970s as EPA shut down most of the refineries. I often drove from I-35 to Enid. In 1970 you could see the Champlin refinery from about 5 miles away. In 1980 you could see it from 20 miles away. (Of course it was no longer a refinery, but at least you could see the structure.) Given that tornados and severe T-storms are Okie specialties, the observation may be relevant.
Polistra was named after the original townsite of Manhattan (the one in Kansas). When I was growing up in Manhattan, I spent a lot of time exploring by foot, bike, and car. I discovered the ruins of an old mill along Wildcat Creek, and decided (inaccurately) that it was the remains of the original site of Polistra. Accurate or not, I've always liked the name, with its echoes of Poland (an under-appreciated friend of freedom) and stars. ==== The title icon is explained here. ==== Switchover: This 2007 entry marks a sharp change in worldview from neocon to pure populist. ===== The long illustrated story of Polistra's Dream is a time-travel fable, attempting to answer the dangerous revision of New Deal history propagated by Amity Shlaes. The Dream has 8 episodes, linked in a chain from the first. This entry explains the Shlaes connection.
