<br />. <br /> <br />~Lltitudes, directed with a component perpendicular and toward the <br /> <br />mountains, more supercooled liquid water developed ~n the clouds. The <br /> <br />. <br /> <br />1;irater was located at lower and warmer altitudes. <br /> <br />This flow with a <br /> <br />c:omponent perpendicular to the mountains occurred in STORM 9 before <br /> <br />frontal passage and for a few hours afterward. <br /> <br />But when the flow at <br /> <br />. <br /> <br />low-altitudes was parallel to the mountains updrafts were weaker and <br /> <br />~'ater release was less and supercooled liquid water was largely absent <br /> <br />at low-levels in the clouds. This parallel flow occurred in STORM 9 <br /> <br />. <br /> <br />starting a few hours after frontal passage. <br /> <br />At this time flow toward <br /> <br />the mountains still remained .at higher altitudes with lift there by the <br /> <br />front itself and by the part of the Tushar Mtns protruding above the <br /> <br />. <br /> <br />frontal surface. <br /> <br />The supercooled liquid water was now concentrated at <br /> <br />this higher altitude. <br /> <br />Accompanying such changes as these ~n the <br /> <br />supercooled liquid water were changes in the precipitation processes. <br /> <br />. <br /> <br />Riming growth was important with supercooled liquid water. at low, warm <br /> <br />~_.--~ .--,,,-,,,,,,,,,,,,,.~;;-- _.--:>~ <br /> <br />altitudes while depositional growth of ice cryst~~s~~minated when the <br /> <br />~'ater was above the frontal surface later in the STORM. <br /> <br />. <br /> <br />In line with the variable nature of winter storms there may be <br /> <br />variations in the efficiency of the storms. Insufficient kinds of data <br /> <br />were collected in the 1985 field program to support a total water budget <br /> <br />. <br /> <br />calculation, but there were other useful kinds of data. The supercooled <br /> <br />liquid water flux across the Tushar Mtns integrated through the depth o~ <br /> <br />the cloud has been calculated and compared to the integrated vapor flux. <br /> <br />. <br /> <br />The precipitation flux integrated up the slopes of the mountains is also <br /> <br />a.vailable. In addition, there is information on rates of water release <br /> <br />in updrafts, amounts of supercooled liquid water, and precipitation <br /> <br />. <br /> <br />rates. <br /> <br />All of this information has been examined and leads to the <br /> <br />I <br /> <br />.: <br /> <br />-xxv~- <br />
