Climate related economic losses

<p>The indicator measures the economic losses from weather and climate-related events. In addition to the annual figures, a smoothed time-series based on 30-year averages is presented. In line with the climate normal period as defined by World Meteorological Organisation, these 30 years average figures reflect trends excluding the substantial climate variability on shorter time scales due to natural factors. The indicator is based on data from CATDAT of RiskLayer.</p>本指标用于衡量与天气及气候相关事件所造成的经济损失。除年度统计数据外，本数据集还提供了基于30年平均值构建的平滑时间序列。根据世界气象组织（World Meteorological Organisation）定义的气候标准期，该30年平均值可反映剔除自然因素导致的短时间尺度显著气候变率后的趋势变化。本指标的数据来源为RiskLayer旗下的CATDAT数据库。
