seasonal variations on our climate. The apparent connection with the AMO and NAO to these climatic variables is frequent enough for us to take notice. User Guide All of the data and relationships described in this report are intended to provide a preliminary insight to the various climatological basin responses to various components of the hydrological cycle. All of the relationship data is presented in tabular and graphical format in an attached Appendix and organized according to the structure of this report. It is important for any potential reader and user of the data to recognize a few key points: 1)The relationship between these climate indices and the predicted value is far from an r-squared of 1.0. Climate prediction and the science of climate have had many breakthroughs in the past decade or so but, there are still likely many breakthroughs to accomplish. 2)Not all variables and seasons will contain usable information as the climate indices have not provided enough definition of our atmospheric and oceanic systems. In some instances the user may glean useful information from an individual index/variable relationship or from the skillful combination of indices. 3)Users are recommended to visually examine the charts of some relationships plotted in the accompanying Appendix, the r or r-squared in some instances may be small but when ‘partitioned’ properly can be of some or increased usefulness. An example of this is in the accompanying charts and figures in the body of this report where the ‘yellow’ regions attempt to delineate the neutral mode of these indices. In many of these defined two-dimensional relationships the values near the ‘neutral’ area of an index are very scattered and other index relationships should be examined. 4) If an HCI is outside one of these ‘zones’ it is recommended that the user consider the segment that the current or expected HCI values resides in and not immediately adjacent values. 5)In the body of this report the most relevant HCI variable that apply to given variable and season are outlined. These indices should be examined first however, other variables maybe examined as well. Division 3 (Rio Grande Basin) The Rio Grande Basin, in Colorado, is unique from a number of standpoints both administratively and climatologically. A map of Division 3 and the administrative boundaries of the Divisions can be found in Figure 3. The unique nature of this basin is 7
