“…Latham et al [2004] extended the hypothesis and lightning models to derive a direct rela-tionship between lightning frequency and precipitation rate. In addition, observations also indicate a close link between convective rainfall and lightning, both for individual (or ensemble) storms [Soula and Chauzy, 2001;Seity et al, 2001] and for long temporal and large spatial domains [e.g., Sheridan et al, 1997;Petersen and Rutledge, 1998;Soriano et al, 2001]. The rain rate-lightning relationship has further been employed to improve the estimation of convective rainfall in specific regions [Tapia et al, 1998;Grecu et al, 2000;Soriano and De Pablo, 2003].…”

[1] Seasonal variations on lightning activity of precipitation systems over south China and Taiwan before and after the onset of Mei-Yu have been observed by the lightning imager sensor (LIS) on board the Tropical Rainfall Measuring Mission (TRMM) satellite. Lightning storms before Mei-Yu onset show higher probability of lightning, higher flash rate, and larger radar reflectivity in the mixed-phase region than the Mei-Yu regime. However, the probability of lightning occurrence with the same threshold of maximum radar reflectivity or ice scattering signature is similar for land systems before and during Mei-Yu season. Oceanic systems show slightly lower probability of lightning even with the same thresholds. Relationships between a set of TRMM-observed parameters and LIS lightning frequency are further examined. For lightning systems over land, the total area of radar echo above 35 dBZ has a closer relationship with lightning flash rate at the temperature between −5°C and −15°C than other parameters. Area of lower radar reflectivity at colder temperature, e.g., area of 20 dBZ at −40°C, is also highly correlated with lightning frequency. The highest correlation between area of specific radar reflectivity and lightning frequency is found at lower temperatures when the oceanic lightning systems are examined.

“…Rivas Soriano et al (2001) studied the relationship between CG lightning and convective precipitation over the Iberian Peninsula during the warm season; they realized that convective precipitation and CG lightning show a similar spatial distribution and demonstrated that the quantification of a relationship between CG lightning and surface precipitation is possible. Tapia et al (1998) have demonstrated the potential use of lightning as a short-term predictor of flash floods produced by localized intense convection.…”

Abstract. The objective of this work is to study the relationship between the number of lightning recorded by a network of lightning detectors and the amount of rainfall recorded by the network of automatic rain gauges, during rainy events in Cyprus. This study aims at revealing possible temporal and spatial "relationships" between rainfall and lightning intensities. The data used are based on the available records of hourly rainfall data and the "associated" lightning data, with respect to both time and space. The search for temporal and spatial relationships between lightning and rainfall is made by considering various time-lags between lightning and rainfall, and by varying the area around the rain gauge which the associated lightning data set refers to. The methodology adopted in this paper is a statistical one and rainy events registered under the European Project "FLASH" are examined herein.

“…Due to the existence of a physical relationship between lightning activity and convective precipitation (Petersen and Rutledge, 1998;Soriano et al, 2001;Kar and Ha, 2003), urban effects on lightning are expected. However, the concentration of cloud condensation nuclei (CCN) can be uplifted by the pollution over the cities, which, in turn, might produce changes in the microphysical processes taking place inside the clouds.…”

Abstract. Cloud-to-ground (CG) lightning flash data collected by the lightning detection network installed at the Korean Meteorological Administration (KMA) have been used to study the urban effect on lightning activity over and around Seoul, the largest metropolitan city of South Korea, for the period of 1989-1999. Negative and positive flash density and the percentage of positive flashes have been calculated. Calculation reveals that an enhancement of approximately 60% and 42% are observed, respectively, for negative and positive flash density over and downwind of the city. The percentage decrease of positive flashes occurs over and downwind of Seoul and the amount of decrease is nearly 20% compared to upwind values. The results are in good agreement with those obtained by and Westcott (1995). CG lightning activities have also been considered in relation to annual averages of PM 10 (particulate matter with an aerodynamic diameter smaller than 10 µm) and sulphur dioxide (SO 2 ) concentrations. Interesting results are found, indicating that the higher concentration of SO 2 contributes to the enhancement of CG lightning flashes. On the other hand, the contribution from PM 10 concentration has not appeared in this study to be as significant as SO 2 in the enhancement of CG lightning flashes. Correlation coefficients of 0.33 and 0.64 are found between the change in CG lightning flashes and the PM 10 and SO 2 , respectively, for upwind to downwind areas, suggesting a significant influence of the increased concentration of SO 2 on the enhancement of CG flashes.
