## Abstract The supply of kinetic energy to a shallow layer of air is considered. The cases chosen for analysis comprise occasions of comparatively strong wind and of fairly small temperature gradient so that the supply of kinetic energy from the vertical flux of total heat is not important at smal

Abstract
A semiβempirical treatment of the vertical diffusion of matter in the lowest layers of the atmosphere is given in the following and shown to be in good agreement with the results of carefully conducted field experiments made over two different types of natural land surface. The present work extends the treatment of diffusion in an adiabatic atmosphere given by Calder (1948) by allowing for the effects of thermal stratification.
The treatment is based on the results of an extensive investigation of vertical profiles of mean wind velocity in the lowest ten metres of the atmosphere (mainly carried out at the Chemical Defence Experimental Station, Porton, Salisbury Plain). A complete account of this study will probably be published as a Geophysical Memoir of the Meteorological Office.

## Abstract The result of Hogg (1939) that the positive and negative conductivities in the air vary with height in the lowest regions of the atmosphere, and the fact of a field strength almost unaltered with height can be reconciled by assuming the rate of ionisation to depend upon the height.
Wind characteristics in the lowest 340m (agl) of the atmospheric boundary layer at Pune (Ho32 N, 73% E, 559 m ASL) have been investigated using the pilot balloon wind observations obtained during the summer monsoon seasons of 1976, 1979 and 1980. Variations in the zonal and meridional components of
## Abstract A procedure is suggested by which an estimate of the ascent or descent of air can be obtained by use of constantβlevel maps and upper air soundings plotted on tephigrams or charts of a similar type. Results obtained by this method are compared with those by other methods. Examples of it
