“…However, some studies shows that cold cloud TB does not necessarily imply precipitation due to the existence of cold cloud tops [1,5]. The relationship between cloud characteristics and their generated precipitation remains unclear and needs further detailed analysis at the pixel scale [6][7][8].…”

Although cumulonimbus (Cb) clouds are the main source of precipitation in south China, the relationship between Cb cloud characteristics and precipitation remains unclear. Accordingly, the primary objective of this study was to thoroughly analyze the relationship between Cb cloud features and precipitation both at the pixel and cloud patch scale, and then to apply it in precipitation estimation in the Huaihe River Basin using China's first operational geostationary meteorological satellite, FengYun-2C (FY-2C), and the hourly precipitation data of 286 gauges from 2007. First, 31 Cb parameters (14 parameters of three pixel features and 17 parameters of four cloud patch features) were extracted based on a Cb tracking method using an artificial neural network (ANN) cloud classification as a pre-processing procedure to identify homogeneous Cb patches. Then, the relationship between Cb cloud properties and precipitation was analyzed and applied in a look-up table algorithm to estimate precipitation. The results were as follows: (1) Precipitation increases first and then declines with increasing values for cold cloud and time evolution parameters, OPEN ACCESSAtmosphere 2014, 5 212 and heavy precipitation may occur not only near the convective center, but also on the front of the Cb clouds on the pixel scale. (2) As for the cloud patch scale, precipitation is typically associated with cold cloud and rough cloud surfaces, whereas the coldest and roughest cloud surfaces do not correspond to the strongest rain. Moreover, rainfall has no obvious relationship with the cloud motion features and varies significantly over different life stages. The involvement of mergers and splits of minor Cb patches is crucial for precipitation processes. (3) The correlation coefficients of the estimated rain rate and gauge rain can reach 0.62 in the cross-validation period and 0.51 in the testing period, which indicates the feasibility of the further application of the relationship in precipitation estimation.

“…The NAW technique represents an evolution of the Griffith-Woodley technique (GW), a life-history-type scheme by Griffith et al (1978) based on combined satellite and radar observations (details on life-history methods are given by Barrett & Martin, 1981). The NAW simplifies the GW method by introducing a computationally efficient procedure entirely based on geostationary satellite IR imagery.…”

“…The relatively straightforward satellite detection of tropical convective cloud systems and the possibility of separating cumulonimbus towers from the stratiform anvil was effectively used in several methods. Among others we recall the Griffith-Woodley technique (Griffith et al, 1978), the Negri-Adler-Wetzel technique (NAW) (Negri et al, 1984), and the convective stratiform technique (CST) (Adler & Negri, 1988). Thresholding methods were also applied to produce rain estimations for periods of ten days or more: see, for example, the application to the River Nile catchment by Todd et al (1995).…”

“…Although the Atlas describes global rainfall patterns beautifully, the absolute values are underestimated by a factor of two or so. Griffith et al (1978) proposed an outstanding method of rain estimation from geosynchronous visible and infrared statellite imagery by including the information on stages of cloud development and their method was successfully tested by the GATE observations. However, this method based on one hourly digital infrared data needs tremendous amounts of computer time to get global-scale rainfall estimates for long periods and may not be practical for the climatological studies.…”
