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
