The applicable analysis of PDSI and self_calibrating PDSI drought indices in southwest China 引用 收藏 分享 摘要 西南地区是中国干旱灾害频发地区,且在全球变暖背景下,干旱发生的频率和程度都有所增加,对农业生产和水资源安全造成威胁。帕默尔干旱强度指数(PDSI,Palmer Drought Severity Index)及在其基础上发......
PDSI updates are infrequent. We present a method to extend PDSI using Global Land Data Assimilation System (GLDAS) data. We provide an updated dataset and code for the method. We discuss the accuracy and bias of the method for various regions. We have high accuracy, with 99.5% of the ...

而EOF分析主要关注的是指标在时空尺度上演进的趋势,我们需要在分析前去掉指标(sc-PDSI)的内涵季节项,对趋势项进行提取。 nc_df_mat = nc_df[,-c(1,2)]trend_decompose <- function(x){ ts_index = ts(x,start = c(1981,1),frequency = 12) temp_trend = decompose(ts_index)$trend na_index = ...
The sc_PDSI can automatically calibrate itself at any location using dynamically computed values and can calculate evapotranspiration using the FAO-56 Penman–Monteith (P–M) equation. However, the correlation of the sc_PDSI(P–M) with some factors that drive drought, such as precipitation (P) ...
2) For monitoring evolution of the fall 2009 to spring 2010 Southwest China drought and spring 2000 Huang-Huai drought, 3-month SPEI could better monitor the initiation, aggravation, alleviation and relief of drought in the two regions, whereas the SC-PDSI was insensitive to drought recovery ...
