Surface Classification Using Conformal StructuresXianfeng Gu1, Shing-Tung Yau2 1. Computer and Information Science and Engineering, University of Florida 2. Mathematics Department, Harvard Universitygu@cise.ufl.edu, yau@math.harvard.edu. Abstract
3D surface classification is a fundamental problem in computer vision and computational geometry. Surfaces can be classified by different transformation groups. Traditional classification methods mainly use topological transformation group and Euclidean transformation group. This paper introduces a novel method to classify surfaces by conformal transformation group. Conformal equivalent class is refiner than topological equivalent class and coarser than isometric equivalent class, making it suitable for practical classification purposes. For general surfaces, the gradient fields of conformal maps form a vector space, which has a natural structure invariant under conformal transformations. We present an algorithm to compute this conformal structure, which can be represented as matrices, and use it to classify surfaces. The result is intrinsic to the geometry, invariant to triangulation and insensitive to resolution. To the best of our knowledge, this is the first paper to classify surfaces with arbitrary topologies by global conformal invariants. The method introduced here can also be used for surface matching problems. Conformal Map

Convective Initiation and Evolution Approaching the Southern New England Coast and Long Island
Kelly Lombardo, John Murray, and Brian A. Colle, Stony Brook University-SUNY 1. Introduction
Although severe convection is not as frequent over the Northeast United States as the central U.S., it still occurs and endangers millions of people. This research aims to better understand the distribution and evolution of convection over the Northeast U.S., especially the coastal-urban region of Long Island and New York City. 2. Data and Methods
First, this poster presents some preliminary results of a convective climatology around the southern New England region using WSR-88D Level III data (2001-2006) at KOKX and the National Lightning Detection Network (NLDN) cloud-to-ground (CG) lightning data (2000-2005). The radar data was interpolated to a 4-km horizontal grid, and only those days with a severe thunderstorm (or tornado) warning in the region were counted. The lightning climatology utilized data from the NLDN from 2000-2005 interpolated to a 10x10 km resolution grid.
For the 1 June 2006 case study, a preliminary WRF-ARW (v2.2) simulation has been completed down to 4-km grid spacing over the Northeast U.S. The WRF was initialized at 0000 UTC 1 June using the NOGAPS and was run using the YSU PBL, WSM-3 microphysics, and Kain-Fritsch on the outer (36-km domain). 3.

What are the convective structures across the NE?
Where do these structures initiate across the domain?
Are there favored regions of initiation?
What ambient conditions support convection initiation in these regions?

There has been little work looking at convective systems over the Northeast. The goal of this research is to understand the evolution of convection over the region. Some motivating questions are…
Provide an example: convection initiating especially in the lee/coastal plain, growing upscale into a linear system that decays upon reaching the ocean.
What is the convective structural distribution across the NE and how does it compare to the Midwest?
What environments support these structures?
Where do these structures initiate?
What is the role of the Appalachian lee in convective initiation?
What ambient conditions support convection initiation in this region?
