The atmospheric anomalies associated with the drought over the Yangtze River basin during spring 2011

Abstract: The middle and lower reaches of the Yangtze River basin (MLRY) suffered a once-in-a-50-year drought during the spring of 2011. The abnormality of the atmospheric circulation in the spring is characterized by the deeper-than-normal trough over East Asia and the northwest Pacific while stronger-than-normal high-pressure system over the west, which results in a stronger-than-normal meridional circulation. Meanwhile, the western Pacific subtropical high is weaker than normal and retreats to the east, so the spring… Show more

“…The total population is 78.5 million, which makes Jiangsu the most densely populated province in China [33]. The worst droughtobserved in the last 50 years occurred in the spring of 2011 [34]. This adverse event increased the demand in drought monitoring and the assessment of environmental and social-economic impacts due to drought events.…”

“…The Yangtze River, the longest in Asia and a major lifeline for China, runs eastward across central and eastern China from the Qinghai-Tibet Plateau. Two severe drought events occurred in the YRB in the last decade, one in the summer of 2006 during an abnormal July-September warming episode, and the other in April-June of 2011 (Dai et al, 2008;Yang et al, 2013;Lu et al, 2014). They affected the lives of millions and resulted in enormous economic losses.…”

“…Traditionally, SST anomalies a few months ahead influence the subsequent regional droughts. However, it is also feasible and common that synchronous SST anomalies are used in the investigation of regional drought events in southwestern China (Feng et al, 2014), the Yangtze River basin (Lu et al, 2014), and northern China (Wang and He, 2015), which may shape synchronous drought-related circulation patterns. In addition, this is convenient for operational application, while forecast SST and 200 and 500 hPa HGT can be retrieved together from CFSv2 products simultaneously.…”

“…As part of the 2011-2014 California Drought, the drought in 2014 alone cost California USD 2.2 billion in damages and 17 000 agricultural jobs (Howitt et al, 2014). China has also suffered from extreme drought events, such as the 2009-2010 severe drought in southwestern China (Yang et al, 2012), 2011 spring drought in the Yangtze River basin (Lu et al, 2014), and 2014 summer drought in northern China (Wang and He, 2015). Because drought is a costly and disruptive natural hazard, reliable drought prediction is fundamental for water resource managers to develop and implement feasible drought mitigation measures.…”
