ELEVElevationElevated ConvectionConvection occurring within an elevated layer, i.e., a layer in which the lowest portion is based above the earth's surface. Elevated convection often occurs when air near the ground is relatively cool and stable, e.g., during periods of isentropic lift, when an unstable layer of air is present aloft.
In cases of elevated convection, stability indices based on near-surface measurements (such as the lifted index) typically will underestimate the amount of instability present. Severe weather is possible from elevated convection, but is less likely than it is with surface-based convection.Normal Water Surface ElevationIn hydrologic terms, the lowest crest level of overflow on a reservoir with a fixed overflow level (spillway crest elevation). For a reservoir whose
outflow is controlled wholly or partly by movable gates, siphons, or other means, it is the maximum level to which water may rise
under normal operating conditions, exclusive of any provision for flood surcharge.
