Abstract: The theory of a number of different techniques for the computation of vertical motion in the atmosphere is discussed. A comparison of two independent techniques shows that both usually yield vertical velocities of the ...

Abstract: Radiative cooling is computed for a warm, isothermal atmosphere streaming out over a cold surface. The study shows that the rate of cooling at heights from a few centimeters up to a few meters varies inversely as the square ...

Abstract: The Air Pollution Division of the State of Pennsylvania has conducted simultaneous measurements of meteorological variables and air quality at Johnstown, Pa. An analysis of the observations for two fall seasons showed that ...

Abstract: Standard deviations of wind direction fluctuations at 76 m at Ris? for the first half year of 1975 have been analyzed as functions of wind speed and temperature lapse rate, either measured near the surface or near the level ...

Abstract: It is shown that, in the lowest few hundred meters, nighttime inversions tend to break down due to onset of turbulence when the Richardson number falls between 0.2 and 0.5. Since the Richardson number is statistically ...

Abstract: After removal of the annual variation, daily temperatures at 17 North American stations were subjected to spectrum analysis. Winter spectra at west coast maritime stations were characterized by energy mostly at periods of ...

Abstract: A paper published in 1948 suggested that there was a correlation of 0.62 between the wind on Jupiter (as indicated by the motion of the Great Red Spot) and mean zonal geostrophic winds at the surface of the earth. Observations ...

Abstract: Ten-day average ?thermal winds? derived from TIROS VII in the CO2 band are compared to the corresponding geostrophic winds at 10 mb at latitudes 40?60N. The correlations for the west-east components are of order 0.8, those ...

Abstract: Various synoptic variables are related to satellite radiation data. It is shown that: (1) Vertical motion is related jointly to window radiation and water vapor radiation. (2) Surface relative humidity can be estimated ...

Abstract: It is shown that a spectrum covering a large range of frequencies can be found by superposing estimates of spectra of means over periods of different lengths. The method is illustrated by the power spectrum of temperature ...
