    • Testing a Flexible Method to Reduce False Monsoon Onsets 

      Reeve, Mathew Alexander; Spengler, Thomas; Chu, Pao-Shin (Peer reviewed; Journal article, 2014-08-08)
      To generate information about the monsoon onset and withdrawal we have to choose a monsoon definition and apply it to data. One problem that arises is that false monsoon onsets can hamper our analysis, which is often ...
