Sentences with phrase «weak cycle»

However, the fact remains that the last very weak cycle with follow up into the current one is completely different than any other 2 cycle period.
«This is the first time we have seen a short and weak cycle since scientists began tracking the solar cycle in the 1700s, following the last grand minimum in the 1600s when there were almost no sunspots... The big question remains: Are we about to head into a grand minimum, as happened during the Maunder Minimum in the 1600s?
On balance the evidence shows that solar is more likely the cause than CO2 but the issue can soon be resolved by observing the global temperature changes that occur as a result of the extended cycle 23 and the probable weak cycle 24.
During that century there were practically no sunspots... There is ample circumstantial evidence that it has a significant impact, such as the Little Ice Age that occurred during the last grand minimum, as well as the unusually cold climates that also matched past weak cycles, now, and also in the early 19th and 20th centuries.»
The biggest solar storm in recorded history, called the Carrington event, occurred at the end of another especially weak cycle in early September 1859.
In 1859, during an otherwise weak cycle, a solar storm made telegraph wires spark, starting fires.
The cooling fears of the 60's and early 70's coincided with weak cycle 20 and the cessation of warming occurred during cycle 23 which has been weaker than the two cycles before it.
Lockwood says the current weak cycle could herald the sun dipping into another extended period of inactivity.
We reanalyze the available group sunspot numbers and suggest that solar cycle # 4 was in fact a superposition of two cycles: a normal cycle in 1784 - 1793 ending at the start of the Dalton minimum and a new weak cycle in 1793 - 1800 which was the first full cycle within the Dalton minimum.
Using the estimated uncertainties, we also calculate new, weighted annual values of in 1790 — 1796 which show a clear minimum in 1792 — 1793 and a maximum in 1794 — 1795, supporting the idea of an additional weak cycle in 1790's.
This is the first time we have seen a short and weak cycle since scientists began tracking the solar cycle in the 1700s, following the last grand minimum in the 1600s when there were almost no sunspots.
On balance the evidence shows that solar and oceanic variations are more likely the cause of recent observations of warming in the air than increasing CO2 in the air but the issue can soon be resolved by observing the global air temperature changes that occur during and after the extended cycle 23 and the probable weak cycle 24.
There is ample circumstantial evidence that it has a significant impact, such as the Little Ice Age that occurred during the last grand minimum, as well as the unusually cold climates that also matched past weak cycles, now, and also in the early 19th and 20th centuries.
The scientists studied 24 men and women (11 of whom were in their 20s and 13 of whom were in their 60s) who lived for more than three weeks in an environment with no time cues other than a weak cycle of light and dark that was artificially set at 28 hours and that gave the subjects their signals for bedtime.
Mysteries remain because eccentricity is the weakest cycle, so should logically not be the dominant cycle for climatic events.
But now new sunspots are moving into view, and a new solar cycle seems to have dawned this past December, which NOAA and other experts expect to be one of the weaker cycles since the 1750s.
This weaker cycle persisted for almost two centuries.»
Avoid companies with large debt because during a weak cycle phase, they may find it difficult to service debt.
A new report from seasoned meteorologists says the sun is «almost completely blank» as the center of the solar system enters its weakest cycle in more than a century.
Before the transition, glacial cycles, consisting of cold ice ages and milder interludes, typically lasted about 40,000 years — but those weaker cycles gave way to longer - lasting icy eras with cycles lasting roughly 100,000 years.
Stanford physicist Leif Svalgaard said, «None of us alive have ever seen such a weak cycle.
More important, it is a weak cycle.
We already had a weak cycle, the SC23, which was much longer than the previous SC21 and SC22 (both ~ 10 years long and probably cause of most of the warming in the late 20th century) and it already had a very significant effect.
Thus a decline in solar energy will have an immediate effect if it occurs at a time when the overall balance of all the oceanic oscillations is negative as now (2007 to date) when the end of solar cycle 23 is significantly delayed and the late start of cycle 24 suggests a weaker cycle than we have had for some time.
Even if a weak cycle occurs and it does affect us, the effects would be relatively contained.
And a weak cycle, as Dr. Biesecker points out, doesn't necessarily mean anything to our climate, volcanoes or not.
He also points out that a weak cycle may not have an effect on our climate; we simply don't know for sure.
Moreover, it's not clear the results from the studies indicate a weak cycle next time around.
