<br />regardless of charge. Collisions having impact angles greater than the critical value resulted in either
<br />bounce, temporary coalescence, or coalescence depending on charge. A satellite drop was produced
<br />with temporary coalescence at the intennediate charges of this experiment. Electrohydrodynamic theory
<br />in plane geometry applied to the conditions for defonnable spheres gave an electric field strength
<br />between the approaching drop surfaces sufficient to cause a surface instability that may aid in drop
<br />coalescence.

<br />
<br />The oxygen isotopic composition of freshly fallen snow has been measured simultaneously with
<br />ice-crystal photography at a high ~titude station in the central Sierra Nevada. These and other
<br />meso- and microscale cloud measurements have been used to study the short-tenn 0180 variations of
<br />ice-phase precipitation from winter stonns. In this study, snow samples collected from six stonn
<br />events in 1985 were used.
