14 January 1982)ABSTRACT We have studied a set of detailed mean horizontal wind profiles obtained with a three-component Dopplersodar. For inversion-capped, convective boundary layer conditions, empirical expressions for the mean horizontal wind and the wind shear in the first few hundred meters of the atmosphere are presented. Theobservations are parameterized with the height of the lowest inversion z~, the Monin-Obukhov length L andthe friction velocity u,. From experimental values and

boundary layer. For instance, all of the secondmoments and the dissipation term are integrated frompartial differential equations in Wyngaard and Cot6's(1974) model. The second-order model developed byZeman and Lumley (1976) requires 12 prognostic differential equations for the higher-order moments, inaddition to the differential equations for the first moments in a dry atmosphere, and the third-order modelfor a moist planetary boundary proposed by Andr~ etal. (1976a, 1978) consists of 33 prognostic

Outgoing planetary radiation Zonal averages of the annual outgoing planetaryradiation at the top of the atmosphere from this as wellas from other investigations are shown in Fig. 3.Since our calculations only extended to 137.5 mb andtherefore did not include the contribution to the outward flux from the stratosphere, we have added theoutgoing stratospheric

satellites, like interferometers. This is mainly the case for studies on thestratosphere and on planetary atmospheres forwhich atmospheric conditions (temperature and/orcomposition) are not very well known or are unknown and must be constantly varied by oftenlarge amounts when adjusting theory to experiment. The approach used in this paper for obtaining acomputationally fast and general line-by-line methodconsists, at first, in using a standard line-by-lineprocedure to derive the transmittances

answer thisquestion we need to know how variable the wind is inthe free atmosphere and then determine what constitutes a representative wind value. Previous investigations of wind variability have usedtheodolite tracking of sequential pilot balloons (Singer1956 ), radar tracking of sequential $imspheres ($ohnson and Vaughan 1978), sequential tracking ofMETRAC (Meteorological Tracking) balloons (Gageand Jasperson 1979), and both aircraft and radar windprofiler data analyses (Gage and Nastrom 1985
