However, although the latter varies significantly from cycle to cycle (as reflected in different cycle magnitudes varying by a factor of 2), the tilt angle exhibits roughly the same variations over all cycles, in accord with the idea of a regular cyclic behaviour (Suess et al. 1993; Cliver & Ling 2001; Alanko - Huotari et al. 2007), depending only on the solar cycle phase and not on its strength.

We're also currently in the liveliest phase of the eleven - year solar cycle so now is the time to seek out this fickle phenomenon.

An additional work, Le Soleil amoureux de la lune, 2014, consists of 12 intimately - scaled ceramic panels, each depicting a different phase of the solar and lunar cycle.

However, if CO2 plays this role it is surprising that climatic proxies indicate that Antarctica seems to have warmed prior to the Northern Hemisphere, yet glacial cycles follow in phase with Northern insolation («INcoming SOLar radiATION») patterns, raising questions as to what communication mechanism links the hemispheres.

4) The AMO might be heading for a cool phase, and this combined with a continued cool PDO, on top of a weak Solar Cycle 24 could prove interesting.

The correlation between the two quantities is 0.85 with p < 0.01 for the whole period studied.It could therefore be concluded that both the decreasing correlation between sunspot number and geomagnetic activity, and the deviation of the global temperature long - term trend from solar activity as expressed by sunspot index are due to the increased number of high - speed streams of solar wind on the declining phase and in the minimum of sunspot cycle in the last decades.»

We are currently more than six years into Solar Cycle 24 and the current nearly blank sun may signal the end of the solar maximum phase,» Vencore Weather experts nSolar Cycle 24 and the current nearly blank sun may signal the end of the solar maximum phase,» Vencore Weather experts nsolar maximum phase,» Vencore Weather experts noted.

CO2 concentrations are meaningless — it's water in all it's phases reacting to variations in solar irradiance brought on by various solar cycles and orbital cycles that controls climate — PERIOD!

Some scientists, however, have been arguing the world is indeed headed for a cooling phase based on solar cycles.

The only things that can change that resultant point of temperature equilibrium significantly are changes in solar radiance coming in and changes in overall atmospheric density (a function of mass and pressure) which affect the radiant energy going out or a change in the speed of the water cycle which, because of the unique characteristics of the phase changes of water altering the speed of energy flow through the system is capable of exerting a powerful regulatory effect.

During the past 5 - 6 years the solar radiation decreased by about 0.2 W / m2 since the sunspot cycle was in its decreasing phase.

The solar application offers the potential for the long - range prediction of SOI behavior and associated rainfall variations, since quasi-periodicity in solar activity results in an expected cycle of situations and phases that are not random events.

I know however that there are also longer solar cycli like the «De Vries» cycle that is just getting in another phase according to for instance prof. De Jager in my country

Since the PDO entered its 30 - yr cool phase in 2008, it would tend to support future falling temps as indicated on the graph, especially in light of weakening solar cycles which also started from 2008, leading to, in scientific parlance, a super-duper double whammy....

This means that every spectral band of the radiation code increases equally (~ 0.1 %) from the minimum to the maximum phase of the 11 - yr solar cycle.

Note, too, TB, that the shape of the peak of the solar cosmic rays alternates between rounded and flattened in each solar eleven year cycle, leaving each phase of the PDO with two of one type and one of the other, and the predominant one alternates, providing a possible mechanism for alternate dominance of Las Ninas and Los Ninos.

Over time, those that are in phase with the solar cycle will tend to strengthen and persist and those that are out of phase will tend to weaken and die.

There are at least 2 papers that talk about a «phase catastrophe» during the Maunder and Dalton minima implying either a period when the solar poles are both the same polarity for an extended period or the cycle goes to 22 years instead of 11, I also think its highly possible that both poles could fluctuate between positive and negative through the entire cycle if the new polar inflows are not strong enough to change the polarity.

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.
