Climate Variability Diagnostics Package (CVDP)#


The Climate Variability Diagnostics Package (CVDP) developed by NCAR’s Climate Analysis Section is an analysis tool that documents the major modes of climate variability in models and observations, including ENSO, Pacific Decadal Oscillation, Atlantic Multi-decadal Oscillation, Northern and Southern Annular Modes, North Atlantic Oscillation, Pacific North and South American teleconnection patterns. For details please refer to the [1] and [2].
