Abstract
Extensions to the Karhunen-Loeve transform applied to complicated phen omena are demonstrated on Rayleigh-Benard thermal convection phenomena . The extensions deal with the role of the mean flow, and with the enh ancement of the robustness of the Karhunen-Loeve basis when used for a range of parameter values, such as Rayleigh number, other than the pa rticular values at which Karhunen-Loeve basis is generated.
