This study would be impossible without the collegial and unselfish help from many in our efforts of collecting the Q1 data. Some directly handed over their data; others made suggestions, even though all did not lead to success. For this, we are grateful to Paul Ciesielski, Steve Esbensen, Richard Johnson, Masaki Katsumata, Yasu-Masa Kodama, Steve Kruger, Wei-Kuo Tao, Wen-wen Tung, Xiaoqing Wu, Michio Yanai, Xiping Zeng, and Minghua Zhang. The authors would also like to thank Robert Houze and Eric Maloney for their comments on preliminary results of this study, Brian Mapes for his detailed comments on a draft of this manuscript, and Shoichi Shige, Courtney Schumacher, and an anonymous reviewer for their specific and constructive comments on the submitted manuscript, which all led to substantial improvement of this article. This research was support by a NASA TRMM/PMM project, Award NNX07AD41G.
