Europe TS Instability

  
Instability: Upper Troughs & Cut off Lows
Instability: MUCAPE & MULI (WRF-NMM)

SB & MU Lifted Index Criteria:

 

0 to -2: WK potential, needs trigger

-3 to -5: MOD potential

< -5: strong potential

 

Note: Good correlation between LI values < -5 and severe weather events

SB & MU CAPE Criteria:

 

300 to 1000: WK convective potential

1000 to 2500: MOD convective potential

> 2500: strong convective potential

 

Note: No correlation between CAPE values and severe weather events

CIN Criteria:

 

> 100: precludes TS development without significant forcing

50: associated with derechoes

=< 25: associated with significant TN
