Frank Pasquill

from Wikipedia, the free encyclopedia

Frank Pasquill (born September 8, 1914 - October 15, 1994 ) was an English meteorologist at the Meteorological Service of the United Kingdom, the then Meteorological Office . He worked in the fields of atmospheric diffusion and micrometeorology .

Life

Frank Pasquill was born the son of the miner Joseph and Elizabeth (née Rudd) Pasquill. He was the first member of his family to attend secondary school in Hartlepool . He then studied at Durham University College , where he graduated with honors in physics in 1935 . He was then awarded a two-year college scholarship. In 1937 he married Margaret Alice Turnbull, with whom he was married for 57 years and had two daughters.

From 1937 to 1943 he worked on the establishment of the Meteorological Office for Chemical Defense in Porton Down . There he dealt with measurements of the evaporation of liquids in turbulent air currents . To do this, he carried out wind tunnel and field tests. On the basis of these experiments, he adapted equations from OG Sutton and thus developed the model of evaporation known today as the Sutton-Pasquill model .

From 1943 to 1946 he worked in Queensland , Australia, toxic to issues of spreading warfare agents known as classified information was classified. In 1946 he returned to the Meteorological Office in Cambridge to lead a working group there. He carried out field tests on evaporation and created height profiles of turbulent flows of heat and water vapor.

In 1950 he earned a Doctor of Science degree from Durham University . He was transferred to the Atomic Energy Research Establishment in Harwell . There he worked with NG Stewart on the spread of radioactive materials from nuclear facilities and nuclear weapons tests .

In 1954 he returned to Porton Down to conduct field tests on the structure of atmospheric turbulence and the spread of pollutants. He developed a simple method for estimating atmospheric stability based on wind speed , global radiation , cloud cover and the time of day . This estimate led to the Pasquill classes of atmospheric stability from A (very unstable) to F (stable). In addition, he derived curves that are now interpreted as vertical and horizontal dispersion coefficients.

In 1961 he moved to the department of micrometeorology in Bracknell . In 1966 he was promoted to deputy scientific director and from 1970 headed a research department on interface meteorology.

In 1974 he retired. He spent a year as visiting professor at Pennsylvania State University and North Carolina State University , working with Hans Panofsky , Kenneth Calder , Frank Gifford and Robert McCormick .

Frank Pasquill was chairman of the Royal Meteorological Society, the Royal Meteorological Society , from 1970 to 1972. In 1978 he was elected honorary member of the Royal Meteorological Society, received its Symons Gold Medal in 1982 and was the editor of a scientific journal of the Royal Meteorological Society, the Quarterly Journal . Member of the Royal Scientific Society, the Royal Society , lampoon in 1977 was.

He wrote a standard work on atmospheric diffusion. From 1962 to 1980 he was chairman of the advisory committee on environmental research of the Central Electricity Generating Board .
