SIGNED: Furrukh Bashir 4 ACKNOWLEDGEMENTS I gratefully acknowledge efforts made by Senator James William Fulbright that culminated as establishment of an international exchange program that allowed me to pursue education and research at Department of Hydrology and Atmospheric Sciences, University of Arizona, that would help me to perform as a better scientist in field of hydrometeorology. I acknowledge the efforts made by United States Education Foundation Pakistan (USEFP), and its head Rita Akhtar, who are trying to educate Pakistani youth and building the capacity of the professional, tirelessly for past several years. I am grateful to Hoshin V. Gupta, Xubin Zeng, James Shuttleworth, Francina Dominguez, Aveline F. Arellano, Paul Sheppard, Elizabeth Ritchie, Christopher Castro, Chuck Weidman, Pieter Hazenberg, Thomas J. Galarneau and Eric A. Betterton, who spent a lot of their personal time with me and kept me motivated throughout this period and never gave up on me. I would say thank you to my fellow students and to administrative and supporting staff of Department of Hydrology and Atmospheric Sciences, especially, to Sandy Holford, Lupe Romero, Sarah Warren, Mike Eklund and Matthew Jones for caring attitude and continuous support. I would say special thanks to Sarah McCormick, Stephanie Sasz, Betsy Barringer and Brian Diffley at Institute of International Education (IIE), and to Joanne Lagasse- Long at International Student Services who were always available, to me in time of need. I am thankful to colleagues at Pakistan Meteorological Department who kept on supporting me, throughout my career. Finally, I am grateful to my mother and wife who endured my prolonged absence from the country and managed chores on my proxy, and I would say thanks to Abeera and Adil for being part of my life. 5 TABLE OF CONTENTS LIST OF TABLES ........................................................................................................................... 8 LIST OF FIGURES ......................................................................................................................... 9 ABSTRACT ................................................................................................................................... 13 CHAPTER 1: INTRODUCTION .................................................................................................. 15 1.1 THE KARAKORAM ANOMALY ....................................................................... 15 1.2 AVAILABILITY OF HYDROMETEOROLOGICAL DATA ............................. 17 1.3 ASSESSMENT OF DROUGHTS IN PAKISTAN ............................................... 17 1.4 OBJECTIVES ........................................................................................................ 19 CHAPTER 2: PRESENT STUDY ................................................................................................. 20 2.1 A HYDROMETEOROLOGICAL PERSPECTIVE ON THE KARAKORAM ANOMALY USING UNIQUE VALLEY-BASED SYNOPTIC WEATHER OBSERVATIONS ....................................................... 20 2.2 DEVELOPMENT OF HIGH RESOLUTION DAILY PRECIPITATION AND TEMPERATURE DATA PRODUCT FOR PAKISTAN ........................... 20 2.3 RECONSTRUCTION OF HISTORY OF METEOROLOGICAL AND HYDROLOGICAL DROUGHTS IN PAKISTAN USING HIGH RESOLUTION IN SITU GRIDDED DATA SETS ............................................. 21 2.4 FUTURE RESEARCH DIRECTIONS ................................................................. 21 REFERENCES ............................................................................................................ 23 APPENDIX A: A HYDROMETEOROLOGICAL PERSPECTIVE ON THE KARAKORAM ANOMALY USING UNIQUE VALLEY-BASED SYNOPTIC WEATHER OBSERVATIONS ............................................................................................................ 29 ABSTRACT ................................................................................................................ 30 1.
