GLOSSARY AND ACRONYMS

Accretion: In cloud physics, the growth of an ice hydrometeor by collision with
supercooled cloud drops that freeze wholly or partially upon contact.

Agl: Silver Iodide

AGL: Above Ground Level

AMS: American Meteorological Society

AlMEl: ATmospheric, Meteorological and Environmental Technologies

CCM: Certified Consulting Meteorologist

CCN: Cloud Condensation Nuclei - particles, either liquid or solid, upon which
water vapor condenses and forms cloud drops in the atmosphere.

CFDC: Continuous Flow Diffusion Chamber

CLW: Cloud Liquid Water - the amount of non-precipitation liquid water in a
cloud, usually measured in gm-3.

CRBPP: Colorado River Basin Pilot Project

CSU: Colorado State University

Cloud seeding: The introduction of agents (e.g. silver iodide) into a cloud to alter
the phase and size distribution of cloud particles for the purpose of modifying its
development or increasing its precipitation.

CoCoRaHS: Community Collaborative Rain, Hail & Snow network in Colorado

Cold cloud: A cloud composed of supercooled water drops and/or ice particles.

Condensation: The physical process by which a vapor becomes liquid; the
opposite of evaporation.

Convection: As specialized in meteorology, atmospheric motions that are
predominantly vertical, resulting in the vertical transport and mixing of
atmospheric properties; distinguished from advection.

Convective cloud: A cloud which owes its vertical development, and possibly its
origin, to convection.
