In paragliding, base denotes the altitude of the lowest cloud layer, typically cumulus clouds, in a given area. This cloud base serves as a critical reference point for pilots. For example, a pilot might say, “The base is at 3000 meters today,” indicating the height above sea level at which the clouds begin to form.
Knowing the cloud base is essential for several reasons. It provides valuable information about thermal activity, which paragliders use to gain altitude. Strong thermals often form under cumulus clouds. Furthermore, understanding the base height is crucial for flight planning, ensuring pilots have sufficient clearance from clouds and can navigate safely. Historically, estimating the cloud base was done visually, but now, pilots often use weather forecasts and instruments to determine its altitude more accurately.
