摘要: SUMMARY The temporal variability of polar sea ice is complex and closely linked to global climate. amount over an area can have a significant effect on the energies transferred between atmosphere ocean. Statistics derived from observations are therefore great interest scientists. We showcase new method analysis which may be used examine annual in formation. demonstrate our using concentration images Earth-orbiting satellites that span several decades. growth melt Antarctic modelled simple two parameter spatial nearest neighbour process treats water as species competing for territory. Simulations model estimate time series representing rates competition. With techniques functional data analysis, these detect both amplitude phase variation, isolate major modes variation Copyright © 2008 John Wiley & Sons, Ltd.
