Both El Niños
show sea level anomalies of up to 8 inches across the eastern tropical Pacific (and corresponding drops in other parts of the ocean basin).

Mike's work, like that of previous award winners, is diverse, and includes pioneering and highly cited work in time series analysis (an elegant use of Thomson's multitaper spectral analysis approach to detect spatiotemporal oscillations in the climate record and methods for smoothing temporal data), decadal climate variability (the term «Atlantic Multidecadal Oscillation» or «AMO» was coined by Mike in an interview with Science's Richard Kerr about a paper he had published with Tom Delworth of GFDL
showing evidence in both climate model simulations and observational data for a 50 - 70 year oscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006
showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in
showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate
Anomaly and Little Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global
sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 measurements).
I would be more than happy to see a tidal chart
showing an estreme
anomaly in
sea level at thesame moment as with observed tidal ice events, but the charts I've seen
show 100 cm tides even at the full moon.
Regarding the «global ice at 1980
levels», here is the canned response we wrote in rebuttal to the astonishingly twisted piece in Daily Tech: What the graph
shows is that the global
sea ice area for early January 2009 is on the long term average (zero
anomaly).
At the same time, the GRACE gravitational -
anomaly satellites, the most accurate method of measurement we have,
showed sea level actually falling from 2003 — 2009.
I've presented videos and gif animations to
show the impacts of ENSO on ISCCP Total Cloud Amount data (with cautions about that dataset), CAMS - OPI precipitation data, NOAA's Trade Wind Index (5S - 5N, 135W - 180)
anomaly data, RSS MSU TLT
anomaly data, CLS (AVISO)
Sea Level anomaly data, NCEP / DOE Reanalysis - 2 Surface Downward Shortwave Radiation Flux (dswrfsfc)
anomaly data, Reynolds OI.v2 SST
anomaly data and the NODC's ocean heat content data.
A comparison of detrended North Atlantic SST
anomalies and scaled NAO (inverted) and NINO3.4 SST
anomalies shows that a change in
Sea Level Pressure preceded the 2001/02 change in the North Atlantic SST
anomalies.
To help
show those multiyear effects, I've animated
sea surface temperature,
sea level, TLT, cloud amount, ocean currents, ocean heat content, precipitation, equatorial Pacific subsurface temperature
anomaly cross-sections.
2) The satellite tropospheric and
sea surface (SST) data differ from the HADCRUT surface temp
anomaly, with the present temperatures of both right at the same
level as in 1991 (while Fig. 1 here
shows an increase over 1991 of about 0.25 °C).
For SON, similar regression patterns are obtained if different atmospheric
levels (e.g. Z1000, Z500) are used instead of Z850, but Z850 was found to have the greatest correspondence with ABS
sea ice
anomalies (not
shown).
These graphs
show sea level pressure
anomalies or differences from average
sea level pressure in the Northern Hemisphere for April, May, June, and July 2016.
The plot above
shows July 2016 Arctic air temperature
anomalies at the 925 hPa
level in degrees Celsius and
sea level pressure
anomalies.
The shrinking of
sea - ice in the eastern Arctic causes some regional heating of the lower
levels of air — which may lead to strong
anomalies in atmospheric airstreams, triggering an overall cooling of the northern continents, a study recently published in the Journal of Geophysical Research
shows.
The observed changes (lower panel; Trenberth and Fasullo 2010)
show the 12 - month running means of global mean surface temperature
anomalies relative to 1901 — 2000 from NOAA [red (thin) and decadal (thick)-RSB- in °C (scale lower left), CO2 concentrations (green) in ppmv from NOAA (scale right), and global
sea level adjusted for isostatic rebound from AVISO (blue, along with linear trend of 3.2 mm / year) relative to 1993, scale at left in mm).
