Solar cycle signals in sea level pressure and sea surface temperature

Abstract: Abstract. We identify solar cycle signals in 155 years of global sea level pressure (SLP) and sea surface temperature (SST) data using a multiple linear regression approach. In SLP we find in the North Pacific a statistically significant weakening of the Aleutian Low and a northward shift of the Hawaiian High in response to higher solar activity, confirming the results of previous authors using different techniques. We also find a weak but broad reduction in pressure across the equatorial Pacific. In SST we id… Show more

“…The second way involves changes in stratospheric temperatures and winds due to changes in UV irradiance (Haigh et al, 2005); this region of the atmosphere has the potential to affect the troposphere and hence the surface climate (Haigh, 1999;Matthes et al, 2006). Although there are studies indicating that both proposed mechanisms are operating Meehl et al, 2009), Roy and Haigh (2010) suggest that the most probable solar influence is by the effect of changes in the stratosphere resulting in expansion of the Hadley cell and poleward shift of the subtropical jets.…”

“…The observed response (Fig. 1b) also shows similarities both in structure and magnitude with the negative phase of the AO/NAO, although there is observational uncertainty in the Atlantic basin depending on the period analysed 16,17 . Quantifying the change in the AO sea level pressure difference between middle-latitudes and the Arctic gives a shift of -1.2 hPa for the model, which is in good agreement with -1.1hPa for the reanalysis.…”

“…A multiple regression analysis of the SLP data are has been carried out, similar to that of Roy and Haigh (2010) except that it incorporates an assessment of the QBO signal. The latter is investigated using both of the approaches as for the zonal mean temperature, viz.…”
