“…And the diurnal variation of the solenoid circulation may contribute to the longevity and propagation of episodes in the vicinity of the eastern TP. Bao et al (2011) employed the theory of mountain-plain solenoid propagation (may refer to Tripoli and Cotton 1989;Carbone and Tuttle 2008) to understand the phenomena of eastward delayed phase for precipitation in the Sichuan Basin. Chen et al (2010) and Yuan et al (2011) suggested that the summertime nocturnal precipitation was attributed to the decreasing stability caused by the low-tropospheric convergence and upward motion, accompanied by a long wave radiative cooling at the cloud top and the weak cold advection from the TP.…”

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.

“…An overview of the process of precipitation retrieval from radar reflectivities over Great is known about how the radar precipitation composite performs over multi-annual scales. Some climatologies from radar-derived precipitation data have been created for the Himalayan region (Houze et al, 2007), USA (Carbone and Tuttle, 2008), The Netherlands (Overeem et al, 2009) and France (Tabary et al, 2012). Radar-based climatologies using space-based radar have also been performed (e.g.…”

The Met Office 1km radar‐derived precipitation‐rate composite over 8 years (2006–2013) is examined to evaluate whether it provides an accurate representation of annual‐average precipitation over Great Britain and Ireland over long periods of time. The annual‐average precipitation from the radar composite is comparable with gauge measurements, with an average error of +23mmyr−1 over Great Britain and Ireland, +29mmyr−1 (3%) over the United Kingdom and –781mmyr−1 (46%) over the Republic of Ireland. The radar‐derived precipitation composite is useful over the United Kingdom including Northern Ireland, but not accurate over the Republic of Ireland, particularly in the south.

“…For example, Rudolph et al (2011) used a 9-year radar data set to investigate the relationship between precipitation and synoptic-scale weather patterns in the European Alps region, while Rudoplh and Friedrich (2013) have studied the vertical structure of precipitation and its seasonality. Previously Carbone and Tuttle (2008) used radar data over the mainland USA to examine the diurnal characteristics of rainfall and the meteorological conditions driving the diurnal cycle (esp. the role of propagating systems).…”

Abstract. Using measurements from the national network of 12 weather radar stations for the 11-year period 2000-2010, we investigate the large-scale spatio-temporal variability of precipitation over Sweden. These statistics provide useful information to evaluate regional climate models as well as for hydrology and energy applications. A strict quality control is applied to filter out noise and artifacts from the radar data. We focus on investigating four distinct aspects: the diurnal cycle of precipitation and its seasonality, the dominant timescale (diurnal versus seasonal) of variability, precipitation response to different wind directions, and the correlation of precipitation events with the North Atlantic Oscillation (NAO) and the Arctic Oscillation (AO). When classified based on their intensity, moderate-to high-intensity events (precipitation > 0.34 mm/3 h) peak distinctly during late afternoon over the majority of radar stations in summer and during late night or early morning in winter. Precipitation variability is highest over the southwestern parts of Sweden. It is shown that the high-intensity events (precipitation > 1.7 mm/3 h) are positively correlated with NAO and AO (esp. over northern Sweden), while the low intensity events are negatively correlated (esp. over southeastern parts). It is further observed that southeasterly winds often lead to intense precipitation events over central and northern Sweden, while southwesterly winds contribute most to the total accumulated precipitation for all radar stations. Apart from its operational applications, the present study demonstrates the potential of the weather radar data set for studying climatic features of precipitation over Sweden.
