60 yr ish’ …Climate Cycle

COLLECTING SOME INFORMATION THIS MAJOR CLIMATE CYCLE FREQUENCY. I have read widely on this topic. About time l got the info together in one spot



A great introduction to start on this topic here

  1. Is there a 60-year oscillation in global mean sea level?

    We examine long tide gauge records in every ocean basin to examine whether a quasi 60-year oscillation observed in global mean sea level (GMSL) reconstructions reflects a true global oscillation, or an artifact associated with a small number of gauges. We find that there is a significant oscillation with a period around 60-years in the majority of the tide gauges examined during the 20th Century, and that it appears in every ocean basin. Averaging of tide gauges over regions shows that the phase and amplitude of the fluctuations are similar in the North Atlantic, western North Pacific, and Indian Oceans, while the signal is shifted by 10 years in the western South Pacific. The only sampled region with no apparent 60-year fluctuation is the Central/Eastern North Pacific. The phase of the 60-year oscillation found in the tide gauge records is such that sea level in the North Atlantic, western North Pacific, Indian Ocean, and western South Pacific has been increasing since 1985–1990. Although the tide gauge data are still too limited, both in time and space, to determine conclusively that there is a 60-year oscillation in GMSL, the possibility should be considered when attempting to interpret the acceleration in the rate of global and regional mean sea level rise.

  3. 70 yr and 20 yr oscillation in China’s climate records

    Climatic regime shift and decadal anomalous events in ChinaWeihong Qian, Xiang Lin, Yafen Zhu, Yuan Xu, Jiaolan Fu
    “Climatic time series from historical documents and instrumental records from China showed temporal and regional patterns in the last two to three centuries, including two multidecadal oscillations at quasi-20-year and quasi-70-year timescales revealed by signal analysis from wavelet transform. Climatic anomalous events on the decadal timescale were identified based on the two oscillations when their positive (or negative) phases coincide with each other to amplify amplitude. The coldest event occurred in the decade of 1965–1975 in eastern China, while the periods of 1920–1930, 1940–1950, and 1988–2000 appeared to be warmer in most parts of China. For the precipitation series in northern China, the dry anomalous event was found in the late 1920s, while the wet anomalous event occurred in the 1950s. A severe drought in 1927–1929 in northern China coincided with the anomalous warm and dry decade, caused large-scale famine in nine provinces over northern China. Climatic anomalous events with a warm-dry or cold-wet association in the physical climate system would potentially cause severe negative impacts on natural ecosystem in the key vulnerable region over northern China. The spatial pattern of summer rainfall anomalies in the eastern China monsoon region showed an opposite variations in phase between the Yellow River Valley (North China) and the mid-low Yangtze River Valley as well as accompanied the shift of the northernmost monsoon boundary. Climatic regime shifts for different time points in the last 200 years were identified. In North China, transitions from dry to wet periods occurred around 1800, 1875, and 1940 while the transitions from wet to dry periods appeared around 1840, 1910, and the late 1970s. The reversal transition in these time points can also be found in the lower Yangtze River. Climatic regime shifts in China were linked to the interaction of mid- and low latitude atmospheric circulations (the westerly flow and the monsoon flow) when they cross the Tibetan Plateau in East Asia.

  4. ROGER ANDREWS has graphed the 60 yr oscillation by latitude. Nice work!!

    “the oscillations occur almost entirely in the Northern Hemisphere and their amplitude decreases towards the Equator”. The graph below shows how the oscillations decrease with latitude. It plots the GISS surface air temperature data because there aren’t enough SST data to plot in the 64-90 (Arctic) latitude band or south of the 24-44S latitude band. The plots are separated to make them visible and each y-axis tick represents 0.5C.

    Superimposed is the 60-year Saturn-Jupiter cycle peaking in 1940.

  5. schwabbe triplets = one phase of AMO / global temp indicator
    12 , 13, 14 (Even odd even) = cool AMO ( Even dominant..JEV align)
    15, 16,17 ( odd, even , odd) = warm AMO ( odd dominant.. J + V with E opposing)

    18,19,20 ( even, odd, even) = cool AMO ( even dominant)
    21,22, 23 ( odd,even,odd) = warm AMO ( odd dominant)

    24,25,26 ( even,odd, even) = cold AMO ( global temp cooling trend)

    Something about the alignments you have specified that correlates with the Quasi AMO 60 yr earth climate cycle

    The shifts occur as a see saw betwen these 2 configurations .

    The table is a plot of J+E+V alignments with each date corresponding with the green peaks on Desmoulins graph above. The odd cycle numbers are J+V with E opposing and even is J+E+V aligned. The G/O rule keeping mainly true. These alignments naturally include the Sun.

    JEV alignment corresponds to a cool phase of AMO and a phase of global cooling in the earths temperature
