“…Regardless, the regressed precipitation in Region 1 (Central North America) and Region 2 (Europe and West Asia) was still relatively higher than in the adjacent regions. In addition, the interannual variability of precipitation in America [ Ropelewski and Halpert , ; Dong and Dai , ] and Europe [ Bice et al , ] is also closely linked to ENSO, which can be explained from the significantly positive correlation over the central region of North America and Europe in Figure e. This implies that the central region of North America and Europe are the regions where precipitation is strongly coupled with soil moisture, but the summer precipitation in these two regions is also closely related to the oceanic impacts.…”

The variability and impacts of spring soil moisture (SSM) over the Northern Hemisphere (NH) in the recent 30 years are investigated. The results show that there are two maximum regions of interannual variability of SSM, which are located in the central region of North America (Region 1), and Europe and West Asia (Region 2). These two regions are crucial areas of land‐atmosphere interaction; SSM in these two regions is closely connected with subsequent summer precipitation in NH. Four simulation experiments show that compared to the oceanic effect, the SSM has a positive contribution to summer precipitation over northern Europe, central Asia, and the southern region of North America but a negative contribution to the central region of North America, Arabia, and India, which accounts for 5%–10% of the summer precipitation based on the regional average. The SSM has significant impacts on subsequent summer precipitation in the midlatitudes, while the oceanic impact is dominant over tropical continents. The regions with remarkable variability of SSM are the areas where the coupling between SSM and summer precipitation is relatively strong. The anomalous SSM over NH primarily influences the general circulation through diabatic heating anomalies and changes the low‐level moisture condition, leading to the anomalies of summer precipitation.

“…A strong periodicity in average sea surface temperatures (SST) in the Atlantic Ocean has also been found and is referred to as the Atlantic Multidecadal Oscillation (AMO). In particular, a strong 65-year cycle in the AMO is evident from 1856 to the present day with a rising trend between 1910 and 1950 and again since the 1970s (Bice et al 2012). The AMO has been correlated with regional changes in temperature and precipitation in Europe, including the United Kingdom (Sutton and Hodson 2005).…”

This paper analyses the temporal and spatial changes in the amount and variability of rainfall in Scotland. The sequential Mann-Kendall test reveals that total annual precipitation has increased across Scotland since the 1970s with increasing trends in variability beginning between the mid-1960s and the mid-1970s. Whilst temporally consistent increasing trends in precipitation totals prevail in the West, many weather stations in the East have experienced subsequent trend turning points in the following two decades, explaining the larger magnitude of the trends in western Scotland in recent decades. Trend analyses on six measures of rainfall variability indicate an increase in rainfall variability during the period 1961-2000, as measured by the intra-annual variance, the winter to summer precipitation ratio, and the annual CUSUM range, with decreasing trends observed in the number of dry days. Periodicities associated with the North Atlantic Oscillation and the Atlantic Multidecadal Oscillation could explain the observed temporal variability of rainfall.

“…We conducted spectral analyses of the various proxy series (MS, CaCO 3 content, δ 18 O, and δ 13 C) separately for the Bottaccione Gorge and Contessa Highway sections in Matlab using fast Fourier transform (FFT) periodogram algorithms modifi ed from Muller and MacDonald (2000). This periodogram method was successfully used for cyclostratigraphic analysis of portions of the Umbria-Marche stratigraphic succession by Cleaveland et al (2002), Mader et al (2004), Brown et al (2009), and Hyland et al (2009), and explained in detail by Bice et al (2012). We performed FFTs of the data (detrended and padded with zeros) in the stratigraphic domain, which yielded a set of spectral peaks representing the stratigraphic wavelengths (periods) of the cycles.…”

We studied a high-resolution multiproxy data set, including magnetic susceptibility (MS), CaCO 3 content, and stable isotopes (δ 18 O and δ 13 C), from the stratigraphic interval covering the uppermost Maastrichtian and the lower Danian, represented by the pelagic limestones of the Scaglia Rossa Formation continuously exposed in the classic sections of the Bottaccione Gorge and the Contessa Highway near Gubbio, Italy. Variations in all the proxy series are periodic and refl ect astronomically forced climate changes (i.e., Milankovitch cycles). In particular, the MS proxy refl ects variations in the terrigenous dust input in this pelagic, deep-marine environment. We speculate that the dust is mainly eolian in origin and that the availability and transport of dust are infl uenced by variations in the vegetation cover on the Maastrichtian-Paleocene African or Asian zone, which were respectively located at tropical to subtropical latitudes to the south or far to the east of the western Tethyan Umbria-Marche Basin, and were characterized by monsoonal circulation. The dynamics of monsoonal circulation are known to be strongly dependent on precession-driven and obliquity-driven changes in insolation. We propose that a threshold mechanism in the vegetation coverage may explain eccentricity-related periodicities in the terrigenous eolian dust input. Other mechanisms, both oceanic and terrestrial, that depend on the precession amplitude modulated by eccentricity, can be evoked together with the variation of dust infl ux in the western Tethys to explain the detected eccentricity periodicity in the δ 13 C record. Our interpretations of the δ 18 O and MS records suggest a warming event ~400 k.y. prior to the Cretaceous-Paleogene (K-Pg) boundary, and a period of climatic and environmental instability in the earliest Danian. Based on these multiproxy phase relationships, we propose an astronomical tuning for these sections; this leads us to an estimate of the timing and duration of several late Maastrichtian and Danian biostratigraphic and magnetostratigraphic events.
