The Rural Voice, 1990-04, Page 49areas that remain critically short of subsoil moisture: parts of Iowa and Minnesota, most of the Dakotas and Nebraska and Kansas. Palmerino acknowledges, however, that an un- usually good timing of rainfall could repeat the 1989 performance, where crops were surprisingly good despite totals far below normal. and volcanic activity. And company experts see a rare coincidence of all these factors portending serious crop problems during the early '90s. They look for events that cause prolonged "blocking patterns" (stationary high pressure systems) in the U.S. corn belt, and note the following: • Developing El Nino conditions Climatologist Dr. Iben Browning says there are two very stormy, crop failure years ahead. In 1990 the rest of our reserves will be used up. In 1991 we will have crop failures and there will be hunger in the U.S. The talk at a crop consultants' conference I attended in Fort Wayne, Indiana on February 27 and 28 went much the same. Fellow consultants from across the midwest are finding it hard to believe that the same incred- ibly timely rainfall can happen again in 1990. There certainly is no subsoil moisture to rely on, and there's been no snow to speak of since January. The lack of volcanic dust in the atmosphere has Paul Handler, an Urbana, Illinois weather expert, con- vinced that there will be no bumper crops for the U.S. this season. But he doesn't see a disaster like '88, either. He thinks it will be much like last year: not enough rain to recharge sub- soil moisture, but enough to produce about 95 per cent of trend -line yields. The last volcano with enough punch to affect weather was the 1985 Colombia eruption. Handler credits the rain -seeding dust it generated with nearly ideal growing seasons in '86 and '87. Another wet spring proponent is Freese-Notis and Associates, the Des Moines -based weather -consulting firm. Charlie Notis says the most sig- nificant weather phenomenon of this winter was the dramatic switch from bitter cold in December to balmy temperatures in January. He has checked weather records and found that virtually every time such a switch has occurred we have had a good crop season. Impending bad news on the long- term weather front describes the out- look for the early 1990s of Cropcast, a Maryland firm. Cropcast combines studies of El Nino, solar/lunar cycles, will have their most pronounced effect on weather and crops in '91 and '92. • Sunspot maximums, which occur about every 11 years, tend to be associated with blocking patterns. A sunspot maximum is due some time between 1990 and 1992. • Though volcanic activity in Alaska last year was much less than the activity of the early '80s, some ash reached the stratosphere, where it can remain for two to three years. This phenomenon will lower average temperatures at higher latitudes, increasing the risk of blocking patterns during subsequent summers. Last but not least, we have clima- tologist Dr. Iben Browning. In the mid -'70s he correctly predicted an in- crease in volcanic and earthquake acti- vity. And a speech he gave Last Octo- ber 9 was followed eight days later by events that proved him on target. He said 1990 and 1991 will be the stormiest years since records have been kept. Each of the past three years, crops have been lower than our utilization, lowering our reserves. We have been profligate. And there are two very stormy, crop -failure years ahead. In 1990 we will use up the rest of our reserves. In 1991 we will have crop failures and there will be hunger in the U.S. "I think the probability is high that the federal govemment will fall, because Americans will take to hunger poorly," Dr. Browning added. "But check me out. On October 16, plus or minus a day or two, there should be a volcanic eruption, certainly some big earthquakes. If that happens, I'm on track." Dr. Browning's expectations proved to be accurate. The San Francisco Bay earthquake hit at 5:04 p.m. Pacific time on October 17.0 SUNSPOTS AND GROWING CONDITIONS Since the early 1800s, astronom- ers have been watching cycles of lunar explosions called sunspots, which seem to reach their peak with amazing regularity every 11 years. Sunspots are gaseous eruptions that throw out huge solar flares containing billions of tons of solar matter. With ever -improved technology, science has been tracking these bizarre solar storms, and NASA researchers are now predicting that the cyclical solar outbursts will reach their next ultimate, frenzied maximum in the years 1990-91. Already things on earth are happening as a result of increased solar activity. In March '89, two great flares erupted, sending their fury of radiation earthward. It knocked many orbiting satellites into a lower orbit. Time magazine reported that a secret de- fence department satellite "began a fatal tumble." Other tracking systems were temporarily suspended. Here on Earth, shortwave transmissions were halted for up to 24 hours, Coast Guard navigation systems were over- whelmed, the Hydro -Quebec power company lost electricity in Montreal, surges in electrical transmission lines across North America were common. Astronomers studying the sun say we are getting a very early start for solar storms of this severity, which suggests we may be entering a period of record-setting solar activity as well as intensity. Solar explosions have been linked to changes in air pressure around the earth, affecting weather patterns, temperature variations, and even the size of the notorious hole in the Antarctic ozone layer. What does it all mean for planet Earth? Crop commodities are at a 22 - month low. Do the sunspots portend depression prices, crop failures, or simple erratic weather?0 APRIL 1990 45
