<br />(as measured by the microwave radionleter on the south edge) <br /> <br />were examined and correlated with the synoptic weather con- <br /> <br />ditions. Nineteen of the episodes ~Iere associated with flow <br /> <br />(at 700 mb) from the south or southwest. Only three of the <br /> <br /> <br />episodes occurred during north or northwest flow. The final <br /> <br /> <br />case was associated with light and variable winds, and <br /> <br /> <br />mountain-generated cumulus during the afternoon hours. <br /> <br />Seventeen of the 23 cases were associated with the passage of <br /> <br /> <br />significant short wave troughs. All of the other six were <br /> <br /> <br />recorded as upper level low preSSUrE! systems passed through <br /> <br /> <br />the area. Each of the three north to northwest cases was <br /> <br /> <br />associated with the passage of a short wave trough around the <br /> <br /> <br />backside of a low center. Invariably, a moist layer was <br /> <br /> <br />detected by rawinsondes between 750 and 650 mb during the <br /> <br />greatest SLW episodes. <br /> <br />Habit Classifier <br /> <br />Software was created to classify 2D-C images by habit as well <br /> <br /> <br />as by size. Rejection criteria are close to universally <br /> <br />accepted procedures. The main difference is in achieving a <br /> <br />"center-in" standard that gives a better definition of the <br /> <br />field of view. A parabolic fit to the number of occulations <br /> <br /> <br />of each diode allows particle acceptance only if the parabola <br /> <br />peaks within the field of view. Size measurements are by <br /> <br />projecting all occulations onto the linear fit to the par- <br /> <br />ticle and measuring the maximum extent. Habit classification <br /> <br />25 <br />
