Roadmap to the Interaction of Binary Typhoons with Topography

Origin from the frequent binary typhoons events in the past years, the idea of interaction of typhoon with topography may change its way. The issue will be more interesting if the number of typhoon is TWO, i.e., the so-called Fujiwhara effect. In the literatures, the binary typhoons problems are investigated primarily with the aspect of vortex merger. Some papers discussed the mutual influence of their vortex tracks (e.g. Wu, 2003). Here I propose several directions for potential research of this issue. The following map is a composite map for my idea.

• Interaction of Binary Typhoons on a Beta-plane.
  We firstly to investigate the problems by choosing typhoons with different combinations of stengths, relative locations, in order to determine or to clarify the basic flow regime of binary typhoons problem.
• The Inclusion of TOPOGRAPHY to the Binary Typhoons system.
  (See the reference map) The inclusion of topography to the binary typhoons will cause very interesting respones to the paths of typhoons, their intensity changes, and their induced circulations around topography. Here the topography is expected to play a sensitive role to disturb the binary typhoons system. The map shows two possible ways of topography inclusion to the binary typhoons system.
  
• Incorporating the problem into the Dynamic model.
  Essentially, this problem can be incorporated into our dynamic model if the interaction is not going to the regime of vortex merger.

I think the above problems are very attractive to the audience of typhoon researchers. I will begins with the numerical simulations using Clawpack to model two Rankine vortices with proper vortex initializations.
