“…Stronger TCs produce more averaged total rainfall, larger averaged rain areas, and higher averaged rain rates. M. Liu et al (2019) also showed that TCs with high intensity tended to produce high rainfall rates, especially toward the storm center. Therefore, the sufficient water vapor supply and the increase in both duration after landfall and the increase in storm intensity at landfall are all responsible for the increasing trend in STC precipitation in the southern coastal area of mainland China except over Hainan Island.…”

“…7e) also show increasing trends, particularly in the southeastern coastal area of mainland China, providing more favorable thermodynamic conditions to slow down the weakening of TCs after landfall. Previous studies have demonstrated that the soil moisture and temperature are critical for TC maintenance and TC precipitation over land (Tuleya and Kurihara 1978;Tuleya et al 1984;Tuleya 1994;Shen et al 2002;Zhang et al 2011;L.

In this study, trends in landfalling tropical cyclone (TC)-induced precipitation over China during 1980–2017 and the involved possible mechanisms are analyzed. Consistent with previous studies, it is found that the total annual TC precipitation shows a distinct spatial distribution with a significant increasing trend in southeastern China but a decreasing trend in southern China. This characteristic is found to be related to the increase in both the annual TC precipitation frequency and the precipitation intensity per TC over southeastern China but to the decrease in the annual TC precipitation frequency over southern China. A noticeable northward shift of total landfalling TC-induced annual precipitation has been identified. It is shown that the precipitation induced by strong TCs (STCs) significantly increased in southern China, whereas that induced by weak TCs (WTCs) increased in southeastern China, with the latter dominating the northward shift of total landfalling TC-induced precipitation over mainland China. The increasing trend of STC-induced precipitation in southern China is found to be closely related to sufficient water vapor supply and the increase in average duration and intensity of STCs after landfall. The increasing trend of WTC-induced precipitation in southeastern China is related to the northward shift of the average landfalling position of WTCs and changes in the environmental conditions that are more favorable for TC maintenance and precipitation.

“…As shown in Tuleya (1994), warm land surface and high soil moisture are favorable for surface enthalpy flux and thus may slow down the weakening of a TC after landfall. Therefore, the increasing trends in land surface temperature and soil moisture provide more favorable surface thermodynamic conditions for TCs to survive longer after their landfall over mainland China (Li and Chen 2005;Park et al 2011;Zhang et al 2011;L. Liu et al 2019).…”

Increasing Destructive Potential of Landfalling Tropical Cyclones over China

This study investigates the trend in destructive potential of landfalling tropical cyclones (TCs) in terms of power dissipation index (PDI) over mainland China in the period of 1980–2018. Results show that both the accumulated PDI and averaged PDI after landfall show significant increasing trends. The increasing trends are found to be contributed primarily by the increasing mean duration of TCs over land and the increasing TC intensity at landfall. Further analyses indicate that the increase in landfalling TC intensity prior to and at landfall, the decrease in intensity weakening rate after landfall, and the northward shift of landfalling TC track density all contribute to the longer duration of TCs after landfall. Moreover, the conducive large-scale conditions, such as the increases in coastal sea surface temperature and land surface temperature and soil moisture, the decrease in low-level vertical wind shear, and the increase in upper-level divergence, are all favorable for intense landfalling TCs and their survival after landfall, thus contributing to the increasing destructive potential of landfalling TCs over China.

“…Previous studies have suggested that evaporation over wet soils is an important (but secondary) factor in precipitation during and after landfall of tropical systems (e.g., Trenberth et al 2007). Liu et al (2019) also showed that evaporation of rainfall was a secondary but nonnegligible effect contributing to 15%-20% of the total rainfall within 100 km of the center of Typhoon Utor (2013).…”

The Hurricane Harvey (2017) Texas Rainstorm: Synoptic Analysis and Sensitivity to Soil Moisture

A synoptic analysis and soil moisture (SM) sensitivity experiment is conducted on the record-breaking rainstorm in Texas associated with Hurricane Harvey on 26-30 August 2017. The rainstorm occurred as the moist tropical air mass associated with Harvey was lifted along a frontogenetical near-surface coastal baroclinic zone beneath the equatorward entrance region of an upper-level jet streak. The weak steering winds in Harvey's environment, allowing Harvey to remain nearly stationary, were associated with a deformation steering flow pattern characterized by a trough to the north and flanking ridges to the west and east. This pattern has occurred with other notable tropical cyclone rainstorms along the Gulf Coast, except in Harvey's case it contributed to the collocation of deep tropical moisture and a persistent midlatitude lifting mechanism. Motivated by marked increases in SM during the rainstorm, a suite of six numerical simulations is used to test the sensitivity of the Harvey rainstorm (track, intensity, and rainfall) to varying SM. These simulations include dry, realistic, and wet SM conditions and an additional three runs with the initial SM held constant throughout the simulations. The results showed that track and prelandfall intensity were most sensitive to SM. Decreased SM resulted in the 1) development of an anticyclone in the southern plains that steered Harvey farther southwest in Texas, and 2) interruption in the intensification of Harvey in the Gulf of Mexico as dry air in the Yucatan Peninsula was entrained into Harvey's circulation, contributing to a weaker system at landfall. Implications of these findings on the evolution of tropical systems are also discussed.
