What are lids?
• Halt convection
• Warmer than surroundings
• Names: Lids(Capping) InversionsRegions of CIN
Stable layers

Why study lids?
• Inhibition of convection
• Allow CAPE to accumulate
• Where do they come from?
• Is there more to lids than meets the eye? i.e. fractal structure of atmospheric layers

Research priorities
• Boundary layer structure
• Lid statistics
• Synoptic origin of lids
• Model representation of lids

Lid analysis
• Collection of as much radiosonde data as possible
• Systematic analysis leading to 4D maps of lid height/occurrence
• Case studies of lid origin
