20111 西非季风概述

2011年西非季风季节总体上接近正常，但降雨量不均匀。在关键的7月至8月至9月（JAS）季节，降雨量的不规则性被证明是难以预测的，因为信号相互矛盾，这凸显了我们继续面临的重大挑战。撒哈拉以南非洲地区降雨量的反复无常对非洲社会和经济产生了深远且往往是可怕的影响，因为该地区的人民依赖它获得食物和水。为了减少这些社区对WAM强度变化的脆弱性，我们迫切需要提高预测的可靠性，以便使他们能够提前计划，各国政府需要采取协调一致的政策，以提高他们科普干旱造成的长期缺水的能力。 随着非洲气候交易所（Afclix）的启动，英国气候社区正在与人道主义部门和非洲政策制定者合作，旨在将最新的气候科学引入政策，以帮助建立撒哈拉以南非洲气候兼容发展的复原力和国内能力。重点是在科学政策界面上的知识共享活动的“立足（非洲）地面”机制。皇家气象学会
The 2011 West African monsoon (WAM) season was, overall, near normal but rainfall was patchy. The irregularity of the rainfall during the crucial July‐August‐September (JAS) season proved difficult to predict because of conflicting signals and this highlights the significant challenges we continue to face for this region. The vagaries of the rainfall in sub‐Saharan Africa have profound and often dire effects on African society and economy as the people of the region depend on it for food and water. To reduce the vulnerability of these communities to variations in the strength of the WAM, we desperately need to improve the reliability of forecasts so as to enable them to plan ahead, and national governments need to adopt coordinated policies in order to increase their capacity to cope with extended periods of water shortages due to drought. With the launch of the Africa Climate Exchange (Afclix), the UK climate community is working with the humanitarian sector and African policy‐makers with the aim of channeling the latest climate science into policies to help build resilience and in‐country capacity for climate compatible development in sub‐Saharan Africa. The emphasis is on ‘feet on the (African) ground’ mechanisms of knowledge‐sharing activities at the science‐policy interface. Copyright © 2012 Royal Meteorological Society
