Fortunately, <br />these were rather numerous and ran the gamut from heavy precipi- <br />tation producers to none and from those episodes that exhibited <br />a significant amount of SLW to some that had very little. <br />During the field season, the precipitation total was just <br />a little above normal for the period but a greater than normal <br />number of storms did pass through the area. There was a strong <br />tendency for the westerly flow from the Pacific Ocean to be <br />split with several of the storms entering the western states <br />at relatively low latitudes. OVerall, the flow was more meridional <br />than zonal leading to a preponderance of plunging type storm <br />systems. Some of these produced significant precipitation <br />and one was in the 20-year storm class. For these reasons <br />it may be difficult to judge just how representative these <br />episodes are of a typical winter period of comparable length, <br />but climatological data presented in a subsequent section <br />(Section 3.2) suggests that except for the greater number <br />of storm days than usual (noted above) the period was fairly <br />typical for any winter period. <br /> <br />Table 3-1 was prepared as an aid in summarizing the most <br />significant features of the 16 episodes in regard to developing <br />a storm and seeding climatology for the Arizona Mogollon Rim. <br />For each of the episodes the table lists: 1) the Medina weather <br />type, 2) the episode duration (in hours) as determined by <br />the presence of SLW at Happy Jack and/or precipitation recorded <br />in the network gauges, 3) the number of hours that SLW (equal <br />to or greater than .01 mm per hour) was recorded at Happy <br /> <br />3-10 <br />
