Research Objectives

• Re-construct the 3D dynamical and moisture fields associated with the boundary using all the observational tools available

• Try to understand why convection occurred on places which are outside the IHOP IOD but not along the boundary the IHOP personnel was working on

Summary and Future Work

• Not enough dynamical forcing along the moisture boundary seems to be the reason that convection does not occur

• Further investigation needs to be done to identify why convection initiated both north and south of the boundary being sampled by the IHOP personnel
