phase» - generating more easterly winds that bring
colder air
from Scandinavia and Siberia to the UK.

phase when the foot or ankle is painful and inflamed.
I have been put off making
cold process soap (starting out with melt and pour) because
from what I have read it is difficult to add different oils and colours because the soap starts to set quickly once it hit the trace
phase.
I'm still in a «transition»

from the cooling circuit, considerably shortening the warm - up
phase with its high loss of friction.
Our analysis of observations
from four years of field experiments indicates that seasonal ice undergoes an albedo evolution with seven
phases;
cold snow, melting snow, pond formation, pond drainage, pond evolution, open water, and freezeup.
Also,
from the same source: http://climateprediction.net/science/secondresults.php «Most models still maintain a temperature of between 13 and 14 Â °C, however some get
colder — these are not stable and the heat flux calculated in
phase 1 was not correct to keep the model in balance.»

We have fairly high confidence that we observe the history of Heinrich events (huge discharges of ice - rafted debris
from the Laurentide ice sheet through Hudson Bay that are roughly coincident with large southern warming, southward shift of the intertropical convergence zone, extensive sea ice in the north Atlantic, reduced monsoonal rainfall in at least some parts of Asia, and other changes), and also
cold phases of the Dansgaard / Oeschger oscillations that lack Heinrich layers and are characterized by muted versions of the other climate anomalies I just mentioned.
We are talking fractions of a second.They say changes in the earth's rotation rate may effect the oceanic circulations, causing them to
phase from cold to warm etc..
Its persistent
phase allowed
cold air to escape
from Antarctica and circle over the surrounding coastal waters.
Getting the ECS
from this initial transient
phase is not likely to be accurate because the warming is mostly in the dry or
cold areas (continents, Arctic) where the moisture feedback can't play much of a global role.
I'd expect a slower sea level rise rate
from the mid 2030's during the next
cold AMO
phase.
In 1976 there was a slight warming thanks to the PDO
phase shift
from its
cold to warm
phase.
If ocean oscillations are as powerful a climate driver as the anti-CO2 alarmists claim then this graph suggests a simple story: that
cold Pacific surface waters swallowed up a big gulp of warmth
from 1940 - 1970, which the PDO then belched back up during its warm -
phase in the 80s and 90s.
According to their modeling studies, the difference in the amount of incoming solar radiation, in this case, primarily in the ultraviolet (UV) wavelengths, during the minima and maxima of the 11 - yr solar cycle are large enough to produce a characteristic change in the winter circulation pattern of the atmosphere over North America... When the NAO is in its negative
phase, more
cold air can seep south
from the Arctic and impact the lower latitudes of Europe and the eastern U.S., which helps spin up winter storm systems.
Also,
from the above, it can be seen the
cold phases coincided ~ 1960 - 90.
For example a conbination La Niña and North Atlantic Oscillation

The LIA represents the
coldest phase of the last 10,000 years when mean temperatures deviated strongly negatively
from the Holocene average and which therefore are hard to justify as a representative pre-industrial baseline.
After all a slightly less
cold upwelling entering the ENSO process
from below would manifest itself in warming at the surface (and vice versa) and that would help to account for the apparent disjunction between the strengths of the La Nina and El Nino
phases in your article.
But you suggested that the 1995/96 rise in Tropical Pacific OHC may have come
from below the 700 meter level, when you wrote, «After all a slightly less
cold upwelling entering the ENSO process

This is why gardeners will put water vapor in the air and water liquid on the ground around their garden on a clear
cold night — it protects the local area
from cooling as fast because water vapor and liquid both 1) cool much slower than dry air due to their massive heat capacity, and 2) cool even slower because they release their massive latent heat, which means that heat energy is released
from them without requiring a drop in temperature — once they're in the latent heat release
phase, they just keep shedding energy without dropping in temperature any further.
Not sure why that's significant, other than since we've been in a temporary
cold phase of the Pacific Decadal Oscillation
from about 2000 - 2013 the record warm years had a slightly lower magnitude.
The climate record derived
from long ice cores taken through the Greenland ice cap suggested that the warm climate of the Eemian might have been punctuated by many sudden and fairly short - lived
cold phases, but these results remain controversial.
The pattern is also associated with the negative
phase of the Arctic Oscillation, which is the dominant atmospheric pattern observed during severe winters and comprises a weakened jet stream and more

from the Arctic into North America and Eurasia.
They include the Atlantic Multidecadal Oscillation (AMO) that exhibited a warm
phase from 1930 - 1965, but with a transient drop between 1945 and 1948, a Pacific Decadal Oscillation (PDO) that shifted
from warm to
cold between 1942 and 1950, and a series of El Nino conditions
from 1939 through 1942.
Well done, that's because there isn't a causal link there, it's a correlation with a profound

from the
cold and warm modes.
