3. Stability

Other Instabilities » MAULs Characteristics

Many MAULs can exceed 100 hPa in depth, extending hundreds of kilometers horizontally. While convective overturning may quickly neutralize many of these MAULs, there may be instances where processes creating the unstable state may act to maintain the layer instability for periods longer than 30 minutes. Such persistent MAULs may occur in the vicinity of the inflow region of some mesoscale convective systems and may help to explain some of the dynamic features observed with these systems.
