Microstructure of Cold Fronts and Implications as to Their Detection by Radar.

Abstract

RE AND COMPARISON OF PICTURES OF RADAR RETURN REVEAL THAT LARGE VALUES OF REFRACTIVITY DUE TO THESE GRADIENTS CAN BE CORRELATED WITH AN ORGANIZED PATTERN OF RADAR RETURN. (2). Wind fields were examined through the front and the presence of 'gust lines', evident in the microscale tower data, was not detected on the radar. (3). Vertical profiles of wind and dry-bulb and wet-bulb temperature were determined by use of the log-power relationship. Some regular changes were noted in the log-power, wind profile variables, but those in the log-power dry-bulb and wet-bulb temperature profiles varied irregularly. Also, roughness length appeared to be a function of stability. (4). Soil and air temperatures through the frontal zone were compared by looking at the variations in flux of soil heat versus the temporal gradients of temperature in the atmosphere, with some regular results.
