Sentences with phrase «by decadal shift»

Not exact matches

In the Swanson and Tsonis paper it is suggested that the decadal variations of the global mean temperature, the climate shifts, observed in the 20th century are basically caused by the synchronization of four modes.

These sudden decadal changes tend to become ameliorated over the 50 year period with shifts rrestricted to 0.25 C except the fifty year period commencing around 1660 which is by far the greatrest shift in the entire CET record.

Wu, Lee, and Liu (2005) said: «The 1970s North Pacific climate regime shift is marked by a notable transition from the persistent warming (cooling) condition over the central (eastern) North Pacific since the late 1960s toward the opposite condition around the mid 1970s... This large - scale decadal climatic regime shift has produced far - reaching impacts on both the physical and biological environment over the North Pacific and downstream over North America.»

In 1976/77 the surface temperature of a vast area of the Pacific Ocean abruptly warmed by several degrees as the Pacific Decadal Oscillation shifted from «cool phase» to «warm phase».

Our results show that hydroclimatic variability in the Southwest has not remained constant over the last millennia, with a shift from low to high variance at the MCA - LIA transition that was accompanied by a change in quasi-periodic variance, from a higher concentration of power in the multi-decadal periodicities during the MCA vs. interannual and decadal periodicities during the LIA.

Recently, the peer reviewed journal Nature took a stab at explaining «The Hiatus» by ultimately suggesting that the Pacific Decadal Oscillation shift to cooling was to blame.

Over the past 60 years, Alaska has warmed more than twice as rapidly as the rest of the United States, with state - wide average annual air temperature increasing by 3 °F and average winter temperature by 6 °F, with substantial year - to - year and regional variability.1 Most of the warming occurred around 1976 during a shift in a long - lived climate pattern (the Pacific Decadal Oscillation [PDO]-RRB- from a cooler pattern to a warmer one.

I have already provided examples of observed real world shifts in global temperature trend going back to 1960 that match very well with shifts in the balance between solar variation and the net global effect of all the separate oceanic oscillations (especially the Pacific Decadal Oscillation which is by far the largest).
