Description of tropopause maps



Tropopause maps
Potential temperature and SLP Pressure, winds, and SLP Heights and SLP
EPV diabatic tendency EPV tendency due to radiation EPV tendency due to latent heating
EPV tendency due to boundary layer, cumulus, and mixing processes

Meteorological plots
3-hour accumulated precipitation Column integrated cloud water and ice mixing ratios 10 meter surface winds and SLP
Model sounding following tropopause potential temperature minimum Time-height profiles averaged within 5K of vortex core Vertical EPV profiles averaged within 5K of vortex core

Composites
