Covariability definition

Webthe covariability of a small number qof trigonometrically weighted averages of the data. The population second moments of the projections therefore correspond to an average of the spectrum (or pseudo-spectrum when the spectrum does not exist) over a narrow low-frequency band. Thus, this paper’s long-run covariance parameters are those from WebMar 23, 2014 · Two types of sliding correlation analyses were employed to investigate the extent of spatial and temporal coherence of covariability: (i) comparing the short-term covariability of neighbouring time-series, and (ii) comparing each time-series with selected regional reference time-series.

McKee, N.J. Doesken, and J. Kleist and in 1993 (McKee et al. 1993).The SPI is used for estimating wet or dry condition based on precipitation variable. This wet or dry condition can be monitored by the SPI on a variety of time scales from subseasonal to interannual scales.
