SECTION IV

SEEDING OPERATIONS

A. Objectives

The objective of cloud seeding in the Muddy Road area
continues to be modification of convective storms with the aim of
increasing rainfall. When there is a potential for hailstorms,
primary emphasis is placed on hail suppression.

A secondary objective of the program is to collect and
archive storm and other meteorological data during the seeding
season. This data, along with rainfall and hail crop insurance
data, will be used in later analysis and seeding evaluation studies.

B. Seeding Methods

1. Cloud top seeding
The application of silver iodide pyrotechnic seed-
ing material at or near the top of newly developed peripherical
storm-turrets was the principal method used for treating the con-
vective storms. --With this technique the nuclei generating flares
can be very selectively and rapidly dropped into the new growth of
threatening storms. Night-time storm coverage continued to be a
part of the cloud-top seeding aircraft tasks. The two turbo-charged
cloud-top seeder aircraft and crews were again based at Lakin so
as to be close to the radar operations center and could utilize the
paved-lighted runway.
2. Cloud-base Seeding
Although cloud~op seeding was the main technique
used in Muddy Road V, the third aircraft, a Piper Comanche 250,
