“…and the minor peak was in the early morning around 0600 LST, which is associated with a wavelike propagation of afternoon convection, mountain-plain circulation, and nocturnal low-level jets (Yu et al 2007;Huang et al 2010;Xu and Zipser 2011). The convection formed during the morning peak is less deep (warmer BT min ) as Xu and Zipser (2011) found with TRMM data and also with a smaller LD and CCSA max (not shown).…”

“…But often the CTH and precipitation intensity are not well correlated, especially over China; for example, warm clouds with relatively high brightness temperatures in satellite measurements often bring heavy rainfall in summer over China (Yu et al 2010). To reflect both CTH and precipitation intensity characteristics, the high temporal (better than 1 h) and spatial (better than 5 km at nadir) resolution geostationary satellite infrared brightness temperature images and the collocated high temporal (30 min) and spatial (8 km) resolution Climate Prediction Center morphing technique (CMORPH) data are combined to study MCSs over China in this study.…”

By combining high temporal and spatial resolution Multifunctional Transport Satellite-1R (MTSAT-1R) infrared (IR) images and precipitation data from the Climate Prediction Center morphing technique (CMORPH), this study tracked mesoscale convective systems (MCSs) from May to August in 2008 and 2009 in the middle of east China with an automatic tracking algorithm based on an areal overlapping methodology. This methodology is adjusted to include those MCSs with a relative weak intensity before formation. The unique advantage of combining high temporal and spatial resolution geostationary satellite brightness temperature images and the precipitation measurements for tracking MCSs is that the cloud-top height along with the coverage and the precipitation intensity can be well identified. Results showed that the MCSs formed most frequently in the southwest Henan Province and at the border of four provinces-Shandong, Henan, Anhui, and Jiangsu-which is east of the convergence zone near the terrain's edge. Locations of the highest cloud tops and of the heaviest precipitation rates did not always match. In addition, the MCSs in the study region tended to first reach the maximum precipitation rate, followed soon by the minimum brightness temperature, then the maximum associated precipitation area, and finally the maximum in system area.

“…The nocturnal precipitation in the Sichuan Basin in summer, i.e. the precipitation reaches its diurnal peak around midnight, becomes a hot topic in the recent decade (Li et al 2008;Yu et al 2007aYu et al , 2009Chen et al 2010;Huang et al 2010;Bao et al 2011;Yuan et al 2011).

The quasi-stationary feature of nocturnal precipitation in the Sichuan Basin and the role of the Tibetan Plateau

The nocturnal precipitation in the Sichuan Basin in summer has been studied in many previous works. This paper expands the study on the diurnal cycle of precipitation in the Sichuan Basin to the whole year. Results show that the nocturnal precipitation has a specific quasistationary feature in the basin. It occurs not only in summer but also in other three seasons, even more remarkable in spring and autumn than in summer. There is a prominent eastward timing delay in the nocturnal precipitation, that is, the diurnal peak of precipitation occurs at early-night in the western basin whereas at late-night in the center and east of the basin. The Tibetan Plateau plays an essential role in the formation of this quasi-stationary nocturnal precipitation. The early-night peak of precipitation in the western basin is largely due to strong ascending over the plateau and its eastern lee side. In the central and eastern basin, three coexisting factors contribute to the late-night peak of precipitation. One is the lower-tropospheric southwesterly flow around the southeastern edge of the Tibetan Plateau, which creates a strong cyclonic rotation and ascendance in the basin at late-night, as well as brings abundant water vapor. The second is the descending motion downslope along the eastern lee side of the plateau, together with an air mass accumulation caused by the warmer air mass transport from the southeast of the Yunnan-Guizhou Plateau, creating a diabatic warming at low level of the troposphere in the central basin. The third is a cold advection from the plateau to the basin at late-night, which leads to a cooling in the middle troposphere over the central basin. All these factors are responsible for precipitation to occur at late-night in the central to eastern basin.

“…Similar results are obtained from the precipitation data of meteorological stations in China from 1991 to 2004, which found the Qinghai-Tibet Plateau rainfall peak occurred around midnight, and the phenomenon of a single peak in the morning or a double peak in the morning as well as afternoon also exists [36]. Moreover, studies on the rainfall duration and the phase of the diurnal variation reveal that the long-duration rainfall events (an event that lasts longer than 6 h) have their maximum around early morning, while short-duration rainfall events (an event of 1-6 h in duration) reach their peaks around late afternoon [37]. These findings are consistent with our observed results.…”

Abstract:Alpine precipitation is an important component of the mountain hydrological cycle and may also be a determinant of water resources in inland river basins. In this study, based on field observation data of the upper Shule River and daily precipitation records of the Tuole weather station during 2009-2015, temporal distribution characteristics of alpine precipitation and their vertical differentiation were evaluated mainly using percentages of precipitation anomalies (Pa), coefficient of variation (Cv), precipitation concentration degree (PCD) and concentration period (PCP). The results indicated that the inter-annual variability of annual precipitation was generally small, with a Pa that was only somewhat larger in low altitude zones for individual years; the inter-annual fluctuation of monthly precipitation increased noticeably, but the Cv and precipitation can be described as a power function. Annual distribution was basically consistent; more than 85.6% of precipitation was concentrated during the period from May to September; PCD ranged between 0.71 and 0.83 while the PCP was located within the 37th-41st pentads. Diurnal variation of precipitation was defined, mainly occurring from 1500 to 0100 Local Standard Time, and displayed a vertical change that was dominated by precipitation intensity or precipitation frequency. The temporal distribution of alpine precipitation has a noticeable vertical differentiation, and this is likely to originate from the diversity of precipitation mechanisms in mountainous terrain areas.
