Abstract:

A time-dependent two-dimensional numerical model was employed to test the hypothesis that a dynamically produced meteorological jump is responsible for increases in precipitation well downwind from the primary seeding area. This hypothesis predicts that such a jump will occur in the predominantly dry airstream moving above the layer of storm cloudiness, and will lie some 65 to 115 kilometers downwind of the seeding-produced equivalent heat mountain. Inputs to the numerical model were typical storm soundings abstracted from a large number of storm observations covering the range of conditions expected in the western part of the United States. An equivalent heat mountain was allowed to grow to a certain maximum size at the lower boundary of the upper airstream over a period of time commensurate with that required to produce primary seeding effects.
