Time variation of the mean sea level pressure over the major Mediterranean area
- 65 Downloads
Based on grid-point data the mean annual variation of sea level pressure (SLP) over the major Mediterranean area is examined by means of a simple mathematical model (harmonic analysis).
In order to study the time series of SLP values the period under study (1873–1980) is divided into three subperiods; positive and negative values of the departures from normal (ΔP) during the 108-year period are noted. Linear trend and power spectral analysis methods are applied in order to find statistically significant trends and periodicities.
