Abstract

In this paper principal component analysis (PCA) and singular value decomposition (SVD) are used to define the importance of the variables contributing to the relationship between the transient latent and sensible heat fluxes and to show their temporal and spatial variation. Both methods of analysis produced 2 very important uncorrelated modes of variability in January and July, indicating that the transient heat fluxes are influenced by few controlling factors. The AA. suggest that these modes of variability represent the influences of the meridional temperature gradient, atmospheric moisture, and activity within the source and sink regions of the transient heat fluxes
