Irving P. Krick (1906 – June 20, 1996) was an American
Early years
Krick was born in
Caltech
Around 1930, he began studying at the
Krick completed his doctoral degree in 1934 and remained at Caltech as an instructor.
Caltech terminated the meteorology department in 1948. In response, Krick left the school to start his own firm, taking with him most of the department staff.[6]
World War II
With the outbreak of
In 1944 Krick was engaged in meteorology support for the upcoming Allied
The controversy was fictionalised in the 2014 play Pressure by David Haig, with Krick appearing as a central character; the play however does not make reference to Petterssen's role, instead making an uncompromising Stagg the hero who, by persuading Eisenhower that he was right and Krick wrong, saved countless lives by insisting that the landing be postponed by a day.
Post-war practice
After leaving Caltech, Krick continued offering commercial long-term weather forecasts. He also added the service of cloud seeding, forcing precipitation in drought-affected areas.
In summer of 1948 Krick performed the first series of 27 airborne cloud seeding tests over central Arizona, dropping up to 300 pounds (140 kg) of ice particles on each flight. Indeed, the seeded clouds released rain, raising water levels in local reservoirs. The "rain makers" admitted that the result had other, natural, causes, but in a year that was one of the driest on record it was a significant success. Financially, the volume of water added by Krick's experiment cost only $2.50, compared to $14 going rate.[11] In December 1949 Krick suggested cloud seeding without resorting to airborne devices; his proposal employed ground-based smoke generators dispersing vaporized silver iodide. A single smoke dispenser set, asserted Krick, could be moved by two wheelbarrows; it theoretically provided cloud-seeding particles for an area of 240 square miles (620 km2). Tests demonstrated a fourfold increase in precipitation.[12] By 1951 his cloud-seeding business had 120 employees and had been hired to seed clouds over 330 million acres (1,300,000 km2) in the western United States as well as parts of Mexico and San Salvador.[13]
However, the American meteorological establishment opposed his practice, asserting his methods of cloud seeding were bogus and the weather could not be forecast for more than five days in the future.[ During the mid-sixties, Irving P. Krick & Associates operated a successful cloud seeding operation in the area around Calgary, Alberta. This utilized both aircraft and ground-based generators that pumped silver iodide into the atmosphere in an attempt to reduce the threat of hail damage. Ralph Langeman, Lynn Garrison, and Stan McLeod, all ex-members of the RCAF, attending the University of Alberta, spent their summers flying hail suppression. A number of surplus Harvard aircraft were fitted with racks under each wing containing 32 railroad fuzees that were impregnated with silver iodide. These could be ignited individually or all at once, depending upon the threat. In coordination with ground units, the aircraft would lay a plume of silver iodide in front of approaching cumulonimbus clouds with noticeable effect. Large, active CBs were reduced to nothing. Heavy hail storms were reduced in intensity. [citation needed]
This effective program [citation needed] was funded by farmer contributions and government grants. The program was run each summer and did much to reduce crop damage by hail, otherwise the farm community would not have continued to finance the project. [citation needed]
In 1990 Krick sold his weather business to Strategic Weather Services, renamed in 2000 to Planalytics,[14] remaining with that company as chairman emeritus until his 1996 death from heart failure.[6]
