Rappin et al. (2011) Paper Discussion Patrick Duran 1 of 22
• TC environment is known to have an influence on TC structure and intensification– If the environment is less resistant to outflow…• TC needs to do less work to expand its outflow• More energy available to overcome inflow friction• TC may intensify more rapidly

“Regions with the most persistent convective activity, be it in the storm core or rainband activity, are located radially inward from regions where the strongest rotation feeds most directly into the paths that expand outward toward environments dominated by divergence and low inertial stability (the darker colors).”

• Lower environmental inertial stability leads to more rapid intensification to a TC’s MPI.
• Asymmetries in environmental inertial instability will lead to asymmetric outflow, which is favorable for intensification.– If TC is able to “tap into” low inertial stability, it
might RI.• Convection organizes radially inward of low
