With an UAC in SW Bay near Sri Lanka, we can see the convergence along the coastal belts in mornings with sea being warmer than land.
Once day starts heating up, the easterlies will move in as the convergence shifts inland. So on a single day, you can see how the rains happen with the easterlies associated convergence.
