“…6d). In agreement with Wu et al (2007), the increasing trend in the extreme rainfall per TC is statistically significant in southern Hainan Island. Note that the significant trends were calculated with a sample size of more than 30 TCs.…”

“…Despite the obvious interannual and decadal variations in the annual TC rainfall, the upward trends can be clearly seen at these stations since the 1980s. Wu et al (2007) studied the impact of TC rainfall on Hainan Island during 1962̶2005 and showed that the rainfall amount and the number of days of extreme events related to each TC have been significantly increased, although the number of TCs that affected Hainan Island has significantly decreased over the past four decades due to the prevailing track shifts reported by Wu et al (2005). In this study, the extreme rainfall for each TC at a specific station is obtained by normalizing the annual extreme rainfall with the number of TCs affecting the station (Figs.…”

The torrential-rainfall-associated tropical cyclone (TC) activity often causes flood disasters in China. Moreover, studies suggest that TC-related rainfall rates are likely to increase in a warmer climate. Using daily precipitation observations at 514 meteorological stations during 1965̶2009, this study investigates the primary features of TC rainfall in China, with a particular focus on the contribution of TC rainfall to the changes in the precipitation climate and the average rainfall per TC.TC rainfall mainly affected eastern and southeastern China, accounting for more than 10% of the summer rainfall in South and Southeast China. TC rainfall trended upward in the lower reach of the Yangtze River and Southeast China, contributing to the "wetting in the south and drying in the north" pattern by enhancing the rainfall in Southeast China. This study suggests that the average rainfall per TC has significantly increased in Southeast China during 1965̶2009. In the peak season (July̶September), all significant changes are upward trends that occur south of the Yangtze River east of 110°E. This study finds that the increasing rainfall per TC was not accompanied with the enhanced TC intensity. In addition, no significant trend can be found in the translation speed of TCs that affected China during 1965̶2009, suggesting that the increasing TC rainfall per TC in China was not due to the slowdown of TC movement.

“…For instance, Shephard et al [7] found that TCs accounted from 8 to 17% of cumulative rainfall during hurricane seasons at different locations along the coastal southeastern United States. Wu et al [8] pointed out that TCs produce more than one third of the total precipitation between June and November at Hainan Island in China. A TC that is close to the Pacific coast of Mexico may contribute from 20 to 60% of seasonal rainfall along coastal regions of Mexico, and up to 30% in landmass of western Mexico [9,10,11].…”

Contribution of tropical cyclones to seasonal precipitation over the tropical Americas

Tropical cyclones (TCs) are an important element of the climate dynamics in the tropical Americas. They produce intense precipitation during a few days of the rainy season. The contribution of tropical cyclone precipitation to seasonal accumulated rainfall may be as large as fifty per cent, particularly in the arid and semi-arid regions of northern Mexico. A positive trend in the number of tropical cyclones over the eastern Pacific, has resulted in more of these systems approaching the Baja peninsula and a positive trend in annual precipitation. However, the contribution of TCs to regional accumulated may be positive or negative depending on the trajectory followed by the system. If the TC is not close enough to the coastal region, it may induce atmospheric moisture divergence over land, reducing the chances of tropical convective activity and rainfall. Years of large but "distant to continent" TC activity result in negative anomalies in precipitation for some regions of the tropical Americas. Seasonal regional climate predictions or regional climate change scenarios provide information on TC activity but not on preferred trajectories. By means of TC cluster analysis, the preferred trajectories of TCs around the tropical Americas are explored in relation to quasi-stationary circulations at the steering level. Some ideas on how to estimate preferred TCs trajectories for a season are given.

“…In other words, more precipitation falls in a shorter period in the north, suggesting that more short-duration storms occur in this region. Wu et al [29] also found that the heaviest 1% of daily precipitation contributes 23% of the annual precipitation in Hainan Island. In our study, at least 80% of the total precipitation is found to fall in the 20% rainiest hours.…”

“…In line with IPCC findings [1], the frequency and intensity of extreme precipitation events was found to exhibit increasing trends corresponding with observed global warming. According to Wu et al [29], extreme events contribute significantly to variations in the extreme precipitation amount, as well as in the total annual precipitation. During the period from 1962 to 2005, both the number of days and the total precipitation associated with extreme events slightly increased in Hainan Island.…”

Abstract:To analyze extreme precipitation patterns in Hainan Island, hourly precipitation datasets from 18 stations, for the period from 1967 to 2012, were investigated. Two precipitation concentration indices (PCI) and 11 extreme precipitation indices (EPI) were chosen. PCI1 indicated a moderate seasonality in yearly precipitation and PCI2 showed that at least 80% of the total precipitation fell in 20% of the rainiest hours. Furthermore, the spatial variations of PCI1 and PCI2 differed. Linear regression indicated increasing trends in 11 of the calculated EPI. Principal component analysis found that the first recalculated principal component represented the 11 EPI. The recalculated principal component revealed an increasing trend in precipitation extremes for the whole island (except the interior section). Trend stability analysis of several of EPI suggested that the southern parts of Hainan Island, and especially the city of Sanya, should receive more attention to establish the drainage facilities necessary to prevent waterlogging.
