“…The several days of drought during a crucial vegetation growth period can lead to severe harmful effects. However, the daily SPEI can monitor and assess drought at all timescales, from daily, weekly, monthly, to any longer scale, that is, the daily drought index can fill a void in the capability to monitor the onset and duration of droughts (Lu et al , ). As a result, development of the daily SPEI is urgently needed, the daily SPEI data for shorter scales or longer scales can monitor meteorological drought or hydrological drought, because calculation and application of the daily SPEI are similar to monthly SPEI which can identify different drought types (meteorological drought, agricultural drought and hydrological drought) according to multi‐time scales (Wang et al , ).…”

Drought is a major natural hazard that can have devastating impacts on regional agriculture, water resources and the environment. To assess the variability and pattern of drought characteristics in the Huang-Huai-Hai (HHH) Plain, the daily Standardized Precipitation Evapotranspiration Index (SPEI) is developed based on daily meteorological data in this study. The daily SPEI data are used, including Annual Total Drought Severity (ATDS), Annual Total Drought Duration (ATDD) and Annual Drought Frequency (ADF), which were calculated from 1981 to 2010 at 28 meteorological stations. We used the indices (ATDS, ATDD and ADF), Hovmöller diagrams and the reliable no parameter statistical methods of the Mann-Kendall test to assess the variability and pattern of drought characteristics for the period from 1981 to 2010 in the HHH plain. The results suggested that severe drought occurred in the 1980s, the late 1990s and the early 2000s, severe drought events occurred in 1981, 1986, 1997 and 2002. Decreasing trends for both ATDS and ATDD were found, and the drought situation did not worsen under global warming during the past 30 years, and the drought situation is alleviating in the entire HHH plain. The northeast and southwest regions of the HHH plain have suffered from more severe drought, and the north region is prone to drought. The results of the study can provide a scientific understanding for the adoption of countermeasures of regional defence against drought and also may serve as a reference point for drought hazard vulnerability analysis.

“…In the 2000s, extreme droughts occurred more frequently, such as the winter-spring drought in southwest China in -2010(Lu et al, 2011Zhang et al, 2012a;Zhao et al, 2013) and the spring-summer drought in the middle and lower reaches of the Yellow River in 2011 (Lu et al, 2013), which indicate that China is undergoing an increasing risk of drought under the changing environment. Therefore, it is of great importance to investigate drought risk, which can help to make preparation plans to reduce the adverse impacts of droughts.…”

“…For example, on average drought causes $6-8 billion of damage per year in the United States (Dai, 2011), and reduction of 30 million tons per year in crop production in China (http://politics .people.com.cn/GB/1027/3271796.html). In particular, global warming can exert long-lasting impacts on global hydrological cycle (Lu et al, 2014a). Changes in hydrological cycle, such as precipitation redistribution and evapotranspiration, should consequently alter the wet/dry conditions to some extent.…”

Southwest (SW) China is a drought prone region. Knowledge of the risks and coupling characteristics of drought duration and severity is essential for hazards mitigation and water management. Based on probability distributions, copulas, Mann–Kendall test, overlapping moving windows approach and the self‐calibrated Palmer Drought Severity Index (PDSI) at 69 stations (1959–2013), this study focused on the trends and spatial variability (SV) of (joint) probability drought duration and severity in SW China, and further investigated the potential contributors by analysing the behaviours of precipitation (P), temperature (T), relative humidity (RH), wind speed (WS), atmospheric moisture flux (MF) and divergence (MFD). In particular, the SV was represented by the standard deviation, the drought duration and severity were characterized by the number of months with PDSI < −0.5 in a year [drought months (DM)] and the absolute mean PDSI in drought months (DS), respectively. Results showed that, the DM, DS, DM5, DS5 (5‐year return levels for DM and DS) increased by 0.058 month year−2, 0.012 month−1 year−1, 0.039 month year−2, and 0.009 month−1 year−1, respectively, and the joint return period T(DM > 4, DS > 2) decreased by −0.20 year year−1. Furthermore, due to the decreasing SV in P, T, RH, WS, MF, and MFD, SV of DM5, DS5 and T(DM > 4, DS > 2) significantly decreased in the past decades, by −0.003 month year−2, −0.006 month−1 year−1 and −0.03 year year−1, respectively. These results indicated that drought risks and severity increased significantly in the past decades over SW China. Most importantly, the decreasing SV implied that drought risks and severity might have become more homogeneous in this region. In other words, droughts became more widely spread throughout SW China in the past decades. Therefore, water agencies and governments should be more proactive in seeking measures to improve water resources management and drought mitigation in this region.
