“…This plot shows that R is 3 -4 % throughout the middle troposphere between 3 and 7 km. This value is almost consistent with the observed value of the contribution of precipitation by the TCs (Jiang and Zipser 2010;Rodgers et al 2000;Kamahori 2012). The change in R between the CTL and GW experiments seems small except for the upper troposphere above 10 km.…”

“…(5) Probability distributions are much different among the basins, and the TCs in WP are the most intense. Rodgers et al (2000) and Rodgers et al (2001) estimated TC rainfall amounts from the SSM/I observations within a 444 km radius of the TC center. On the other hand, Jiang and Zipser (2010) defined TC rainfall as that observed within 500 km from the TC center.…”

“…Observational studies utilize satellite-borne instruments as well as ground-based weather radar and aircraft reconnaissance. Rodgers et al (2000) and Rodgers et al (2001) estimated TC rainfall amounts from the Special Sensor Microwave Imager instruments (SSM/I) on board the Defense Meteorological Satellite Program (DMSP) satellite within a 444 km radius of the center of TCs, in the North Pacific and the North Atlantic Oceans, respectively. They found that TCs contribute 7% of the rainfall to the entire domain of the North Pacific and 4% of the rainfall to the entire domain of the North Atlantic during TC season.…”

The mean features of precipitation distribution associated with tropical cyclones are evaluated as anomalies from environmental precipitation fields, in six tropical cyclone active basins, using satellite-derived daily precipitation observation. A common feature in all basins is that concentric positive precipitation anomalies extend within a 5-degree radius from the tropical cyclone center with maximum values of 70 to 100 mm day −1 . These distributions are well approximated by a Gaussian curve with an e-folding radius of 2.2 to 2.8 degrees. Positive precipitation anomalies are surrounded by negative anomalies in all basins, indicating suppression of precipitation due to the tropical cyclones themselves at a large distance from the center. The negative anomalies have minimum values of −2 to −3 mm day −1 and are distributed mainly on the equatorial side of the center. Precipitation excess frequency around the tropical cyclones is also evaluated. The western North Pacific has maximum values of excess frequencies in all basins, in which the frequency for 100 mm day −1 is 26 days yr −1 and that for 200 mm day −1 is 1.8 days yr −1 within a 1-degree radius from the center. We assume that tropical cyclones in the western North Pacific have the greatest precipitation intensity.

“…Several studies have examined the rainfall associated with TCs (hereafter called TC rainfall). For example, Rodgers et al (2000) estimated TC rainfall in the North Pacific using Special Sensor Microwave Imager (SSM/I) observations for an 11-year period. They found that TCs contributed 12% of the climatological rainfall over the western North Pacific (WNP) from June to November.…”

This study investigated the characteristics of the rainfall associated with tropical cyclones (TCs), using the TC best-track data and daily rainfall data from 15 meteorological stations for the period 1961−2008 for the coastal region of Vietnam. In addition to investigating the TC rainfall amount, we estimated the TC rain ratio and the ratio of TC heavy rainfall days (TC_R50) and interpreted these parameters for El Niño and La Niña years. Our results show that the maximum TC rainfall occurs from July to September in the northern region, whereas the total rainfall at southern stations is mainly composed of non-TC rainfall. The TC rainfall amount is concentrated in the central region, with a peak in October-November. The TC rain ratio varies from 0 to ~25%, showing a maximum value in the region of 16°N−18°N in September. The mid-central region of Vietnam has maximum TC_R50 ratio in September-October corresponding to its highest TC frequency in the same period. During El Niño (La Niña) years, the TC rain ratio and TC_R50 ratio in the central region show a significant decrease (increase) in October-November. The La Niña phases more strongly affect TC rainfall than the El Niño phases, particularly in central Vietnam. IntroductionTropical cyclones (TCs) regularly threaten many countries, bringing dangers such as disastrously heavy rainfall and flooding. Several studies have examined the rainfall associated with TCs (hereafter called TC rainfall). For example, Rodgers et al. (2000) estimated TC rainfall in the North Pacific using Special Sensor Microwave Imager (SSM/I) observations for an 11-year period. They found that TCs contributed 12% of the climatological rainfall over the western North Pacific (WNP) from June to November. They also showed that TC rainfall increased from 12 to 18% during El Niño events. Englehart and Douglas (2001) investigated the role of tropical storms over the eastern North Pacific in the rainfall climatology of western Mexico and showed that tropical storm-associated rainfall normally constitutes 20 to 60% of rainfall along Mexico's Pacific coast. In more extreme cases, they found that such rainfall can contribute as much as 25 to 30% to seasonal rainfall totals in western interior locations. Gleason (2006) estimated the characteristics of TC rainfall in the United States between 1950 and 2004. They found that coastal and near-coastal regions received 8 to 16% and 4 to 12% of the precipitation by TCs, respectively. Ren et al. (2006) reported that the ratio of annual TC precipitation to total annual rainfall is 20 to 30% in most of Taiwan and along the coast of China south of 25°N, using rain gauge data over China during 1971−2004. Kubota and Wang (2009 investigated the effect of TCs on seasonal and interannual rainfall variability over the WNP by analyzing rainfall data at 22 rain gauge stations. They showed that along 125°E and between 18°N and 26°N, TC rain accounts for 50 to 60% of the total rainfall during the TC season from July to October. In addition, they described some cha...
