The problem of development of instrumentation for providing wind speed and direction information directly or indirectly to a pilot in the cockpit is considered. The pilots need for horizontal wind information at various stages of flight (i.e., at liftoff, in approach and departure corridors, and even in flight outside the terminal area) are emphasized.
Review of temperature spectra at three levels in the planetary boundary layer covering a range of periods from about 5 hr to 35 days. Apart from the diurnal and semidiurnal oscillations, there are two identifiable period lengths of interest. One extends from about 3 to 7 days, the other from 7 to 20 days. Comparisons are made between these spectra and those reported by other investigators.
