All soundings were plotted on <br /> <br />skew i-log? diagrams and overlayed in temporal and spatial analyses to <br /> <br />show the temporal and spatial variability of each event. Analyses show <br /> <br />large mesoscale variations among the seven rawinsonde sites in nearly <br /> <br />all types; however, each type of event retained its own properties of <br /> <br />stability and moisture which can be used to distinguish it from the <br /> <br />others and predict the relative intensity of convective development and <br /> <br />rainfall. <br /> <br />48 <br />
