The Nature of Intermediate-scale Cloud Spirals
Author: Linwood F Whitney (Jr)
Publisher:
ISBN:
Category : Cloud physics
Languages : en
Pages : 74
Book Description
The purpose of this investigation was to learn the nature of the so-called 'secondary' cloud spiral and associated cloud enhancement that is viewed by satellites. Eight case sequences of two or three days each were compared with their mid-tropospheric vorticity fields and each of the various forcing function fields contributing to vorticity production at sea level. In the situations studied, it was found that the cloud spirals could be related to mid-tropospheric vorticity maxima associated with short-wave systems moving through the larger scale patterns. Thermal advection (namely, the Laplacian of thickness advection in the 1000-mb. to 500-mb. layer) was at least as significant as the mid-tropospheric (500-mb.) vorticity advection in areas of cloud enhancement. It is important to note that the contribution of the thermal term may be either positive or negative, so that sometimes it serves to diminish and at other times to augment the effects of vorticity advection. Generally speaking, as the cloud system develops or becomes better organized, its effects become more positive. The other forcing functions examined, including that one involving the sensible heat exchange with the ocean surface, appeared to have had negligible or minor effects. (Author).

The Airborne ITPR Brassboard Experiment
Author: William L. Smith
Publisher:
ISBN:
Category : Radiation
Languages : en
Pages : 84
Book Description
A preprototype (brassboard model) Infrared Temperature Profile Radiometer (ITPR) was tested on the NASA Convair-990 aircraft expedition during June 1970. The objectives of the airborne ITPR experiment were to obtain data to test various techniques planned for deriving temperature soundings from spaceborne ITPR measurements and to specify the transmission characteristics of the atmosphere and clouds. This paper describes the instrument and shows various results obtained from the airborne measurements.
