As with all previous manned space flights, specialized weather support was required for the Apollo 14 mission. Following climatological studies and daily forecasts for prelaunch work, forecasts were made for the launch, for a number of possible emergency landing areas, and for the planned end-of-mission area.
Showery weather at the launch site led to a 40-min delay—to avoid the risk that lightning might be triggered during the vehicle's passage through thick cumulus clouds. The weather for the landing and recovery operations was good.
A comparison of weather requirements in the various missions since the first manned space flight shows changing and generally, but not always, more relaxed criteria. The meteorologist's ability to meet the weather requirements has been aided by the development of a variety of meteorological satellite products and by improvements in computer-derived guidance material.
