Lecturer Sees Future For Weather Research
Though weather modification techniques have yielded little more success than the Indian rain dances, future prospects are promising. Wilmot N. Hess, director of the National Oceanic and Atmospheric Administration (NOAA), said last night.
Hess, a specialist in weather modification techniques, delivered the annual Sigma XI National Lecture. Sigma Xi is the nation's largest scientific research society.
"I hope to make you a skeptic on weather modification," Hess said, "because any preconceptions like stopping tornadoes are just not feasible."
The NOAA researches weather phenomena and the prospects for predicting the speed and paths of tornadoes, lightning strikes, hurricanes, hurricane reduction, raindrawing and hail prevention.
Cloud seeding is the main process in weather modification, Hess said, and involves dropping hundreds of silver iodide flares from airplanes into cumulus clouds. They increase the amount of cloud iodide, and their effect is to cool water droplets on small ice particles, he said.
THIS PROCESS leaves heat in the cloud, expanding it and allowing for more precipitation, said Hess. He said that the average rain coming from a seeded cloud covered 300 acres feet of rain and an inseeded cloud covered about 100 acres feet of rain.
To date, only four successful rainmaking experiments are on record.
A mathematical process, which determines the quality of the cloud, is the basis for seeding a particular area, he said. Temperature and moisture readings are measured and computerized before a decision is made.
"Of course," he said, "to get conclusive results, seed a whole area, not overhang."

"In a drought area, cloud seeding isn't useful," said Heath. "There must be some."
Hess discussed cloud seeding in relation to hail prevention and said that an experiment was now under way in north-eastern Colorado. He said that the experiment would last till 1977 and that there were no conclusive results.
THE SCHEME involves overseeing the cloud in an effort to produce many small ice nuclei instead of the larger, more damaging halites, said Heh. Also he said the net effect would be that the smaller stones would melt before they hit the ground.
In an assessment of the experiment Hess said, "There's a reasonable chance that
"All we are trying to accomplish is a better understanding of tornadoes so that quicker and better warning systems can be devised." he said.
NOAA is presently trying to measure the internal characteristics of the funnels in order to help predict when a tornado will touch down, Hess said. He said that they made measurements yet, though experiments with two new processes had been undertaken.
Hess acknowledged that there was really no point in trying to modify tornadoes but it made sense to do so.
One new process is the Dopper radial method which measures the particle velocity inside a cloud before the funnel forms, he said. From the swirling motion, he can tell if a tornado is forming and thus give the exact location before it touches down.
HESS ALSO discussed moderation in hurriances, emphasizing the importance of cutting down the high winds (as opposed to letting the rain) which cause the most damage.
"By cloud-seeding the eye wall of the hurricane, we can alter the energy flow of the storm, and in this way, we can make the hurricane higher and flatter," he said. "Thus, wind velocity can be cut by as much as 30 per cent."
Hess said he saw hurricanes as the most exciting part of weather modification, but that there hadn't been any real success because of the newness of the research processes and the limited amount of experiments that had actually been performed.
"Yet, there is much promise for the future, and eventually, many of the prospects in weather modification will become reality," he said.
Financial Aid to Freshmen Available as Late as April 1
Freshmen in need of financial aid this school year can apply for a federal Basic Educational Opportunity grant as late as April 1.
The grants, ranging from $260 to $452 per student, are available this school year for the first time through the government's newest educational assistance program.
Fewer than 200 freshmen have received grants so far, according to Jerry Rogers, president of the college.
correction
A headline in yesterday's Kansan implied that students would be excused automatically. However, students must obtain approval from their instructors first.
Students will be excused from their classes to attend the NCAA basketball finals only if their instructors approve, Del Shannon, or for the answer course, said yesterday.
Shankel, in an official memorandum issued Wednesday, asked instructors to be "sympathetic" to students who wanted to go to the finals.
"As usual," the memorandum said, "we would expect that any work missed would be made up and that students would make sure their work was done by their instructors prior to their departure."
"We tried to correspond to anyone who might qualify for the grants by letters," he said.
Rogers attributed the lack of response to the late arrival of the application forms. When the forms arrived in August, high demand for freshmen hot contact with the incoming freshmen.
The Basic Educational Opportunity grant is an entitlement program, and anyone who qualifies for a grant will receive one. Any person who began college after April 1 is eligible.
Next year, the grants will be offered to second year students as well as for first year students. They will provide between $450 and $650 in grants. Students should send students to apply as soon as possible.
Applications for this school year and for the 1974-75 school year are available in the Fiesta website.

Drug Trial Ends in Acquittal
Tom Phillips, 25, of 518 W. 6th St., was acquitted on a charge of illegal sale of cocaine yesterday by a jury in Douglas County District Court.
Phillips was arrested Sept. 11 as a result of an investigation by undercover agents of the Department of Justice.
Two other persons, Mark Cory, 21, and
Eugene Land, 21, both University of Kansas students, were arrested the same day as Phillips as a result of the investigation. They were charged with one count of possession of marijuana and one count of aiding and abetting the sale of cocaine. Both were released on $3,500 bond, and are awaiting trial.
