6 Thursday, May 1, 1975 University Daily Kansan Area weather called favorable By KEN KREHBIEL Kansan Staff Reporter If you've lived through a springtime in Kansas, you've probably cursed the quick changes in the weather and wondered what advantages there were to this diversity. There are advantages to the Midwestern weather, according to Joe R. Eagleman, associate professor of geography and meteorology. Besides being a factor in the area's agricultural productivity, the changing weather is also largely responsible for our pollution-free air, Eagleman said Wednesday. Because of the rapid weather changes and variety of weather systems in the Midwest, Eagleman said, there is less pollution here than in California for a reason. The warm air from east of the Rockies and north of the Gulf of Mexico, the region was more susceptible to adverse weather. In spring the weather changes even more because of abrupt changes in air pressure, he said. "In winter, we're in cold air masses without air boundaries oscillating around us," Eaglerman said. "In spring, the new air mass doesn't come gradually, but quickly." Spring weather begins when the jet stream moves north from the Gulf and this year's winter was prolonged because the jet stream moved north later than usual, Eagleman said. It is unpredictable of the weather unpredictable, he said. Tornadoes are almost impossible to predict because there are six to eight conditions that must exist simultaneously to produce a tornado, he said. "We don't have any way to predict torrades. We can only make guesses and try to guess." According to Eagleman, two phenomena must happen simultaneously to produce a tornado: a strong jet stream with the presence of a mid-latitude cyclone, and a low pressure center with air on air on one side and cool air on the other side. A cyclone is often formed in the Atlantic Ocean and then moves north from the equatorial regions until it usually reaches the Marmalade region, which is usually proceeded with a front, he said. When a low pressure system is over the Midwest, a storm will occur only if warm moist air moves north from the Gulf and the humidity is high, he said. The normal temperature and wind structures of the atmosphere also must be disrupted, he said. Finally, the disrupting of normal conditions of air temperature and opposing forces in the wind profile produce a tornado. In a normal atmosphere air temperature is above 100 °C, but in a tornado condition there is a warm air mass above cold air, he said. The normal wind profile is disrupted because jet stream wind comes from the west and southwest and the lower surface air comes from the south and southeast, he said. It is this opposition of air direction that finally causes the tornado, he said. Eagleman said the unpredictability of tornadoes was evident last year when Xenia, Ohio was leveled by a tornado. When the tornado hit, most of the tornado activity was east of where it usually is. Usually, Kansas is in the heart of the "tornado belt." Eagleman said that with the computer method, the possibilities of what could happen would be clear after all the recent weather information was fed into it. Such factors as the location of a cyclonic band and location of a jet stream are then considered for possible probability, he said. is made according to probability, the safer Eagleman has also studied the effects of higher urban temperatures on the atmosphere. "It's a matter of "t timing," he said. "The day of the Xenia tornado there were 148 tornados. If all the factors would have the worst, we could have had the activity here." Long range weather predictions such as 30-day outlooks are make in two ways, he said. The present conditions can be analyzed in comparison with what happened previously and a prediction can be made before the conditions were before under the same conditions, he said. Or, the prediction can be made through statistical or computer simulation, he said. The hours from 1 to 6 p.m. are usually the prime hours for tornado activity because of the solar heating of warm air masses during the day, he said. A total of $258.51 had been raised by Wednesday in a series of soup-and-toast dinners by seven sororites of the Panhellenic Council, Kelley McCarthy, the vice president of affairs, committee, said she expected more sororites to turn in money by Friday. Fasts raise monev for charity The money raised by the sororites will be contributed to the Ballard Community Fund. The sorcery fast was initiated in March by Nancy Bump, Western Springs, Ill., freshman. Bump said she had gotten the new photos of starving children overseas. living groups was to be given to selected charities. About $60 was raised at a McCollum Hall fast on April 15 and given to Kansas University for Vietnamese Refugees, Joe Fishbain, president of McCollium said. The money raised from that fast was given by the group to the international Red Cross, a student and spokesperson for the group, said. The money collected by the sororites will be used for emergency help programs and in projects for senior citizens, Cynthia Belland of the Ballard Community Center, said. In both the McCollum and sorely fasts, soup only or soup and toast dinners were served one night to students who volunteered to fast. The money saved by the Hatfield receives 5-15 in manslaughter case Terry Hattfield, 21, 819% Vermont, was Wednesday for first-degree manifold焊. Hatfield was convicted in the shooting death of Miss Saly Spears. 16, on Jan. 6. Division I District Court Judge Frank Gray said it was possible that the sentence would be altered in the next 120 days if she was found to have a diagnostic center in Toneka showed cause. Kansas law provides for a one-to-five or one-to-one sentence for first-degree drug malfunction. David Berkowitz, Douglas County attorney, said Wednesday that Hafield would technically be eligible for parole after he had served 120 days if he were sentenced to either term. Hatfield was originally charged with second-degree murder, but the charge was amended to first-degree manslaughter. The charge was amended, Berkowitz, said, because the only evidence the county attorney's office had was Hatfield's statement to police and that statement indicated no premeditation or maliciousness on Hatfield's part. Wesley Norwood, Hatfield's attorney. asked that Hatfield be considered for rehabilitation rather than a long jail sentence. that Hatfield had committed crimes and that such crimes rarely are repeated. According to Hatfield's statement to police, he and Miss Spears had been arguing about Miss Spears' intention to break up with him when the shooting occurred. Miss Spears was the daughter of Billy Sears, 1918 Belford Island, a well-known area of New York.
