Tropical storms are one of the most impressive weather phenomena.   There is always this curiosity and wonder into such an intricate piece of mother nature.   One moment, there is awe and amazement from this beauty.  The next moment, lives are broken forever.  I was five years when Hurricane Katrina had opened up the gates to flood all of the inner city of New Orleans.  Although I was young and had just moved into the area a month before, I saw and felt the sadness and the grief.  Landfalling Tropical cyclones take a toll on the economy, jobs, and most importantly, life itself.  To reduce this destruction, landfall research is needed to mitigate the worst impacts and better prepare all those near the shorelines of landfall (Webb et. al 1995).
The meaning of the word landfall is vague to most people. Technically, it clearly describes the moment when the eye of a tropical storm reaches the land, but there are land effects to this storm before it even reaches this moment.  For example, convective cloud cover measured by GRIDSAT from the storm usually reaches land before landfall.  The storm intensity and size can change during this interval.  As a result of a TC moving largely over land, the storm usually weakens and dies off quickly into the synoptic flow (Tuleya & Kurihara 1978).  Certain characteristics of the storm could change at different rates in the different parts of the process of a landfall. When we look at variables of the storm such as the minimum surface pressure within it or the maximum sustained wind speeds around it captured by HURDAT, we do see that they decrease after landfall (Bhowmik et. al 2005).  The timing of this transition is still a research question due to various environments that the tropical system surrounds itself with(Vickery et. al 2009).
