WINTER SEASON 2015/16 - ENTERING SOLAR MINIMUM

The emerging sleep of-the-Sun, with only three (3) identified sunspots visible on the solar disk as of 
November 25, 2015.  
Originally prepared: November 23, 2015 (Facebook timeline-post) 
I would like to talk about El Niño, that has made significant headlines in the media. El Niño "The Boy", which is an unusual warming of Pacific sea surface temperature (SST) anomalies, is NOT basin wide through the equatorial Pacific Ocean. In fact close observation shows there is NO comparison to the 1997/98 super El Niño, as this particular event is *Central-to-West-based and NOT basin wide or East-based. This means the warming of SST anomalies over the Pacific is concentrated from the International Dateline, points east to the *Central / North American continent.
A *Central-to-West-based El Niño will in-fact encourage an energized sub-tropical jet-stream but ridging (above normal heights) over western North America due to the area of above normal SST's concentrated through the eastern Pacific, that will tend to encourage troughing (below normal heights) over eastern North America.
What is the foundation of the 2015/16 Winter season?
1. Solar Minimum / High Latitude Blocking - it's very important to consider that we are now entering a solar minimum following the 9-11 year sunspot cycle. The Sun has been averaging 20 daily events or less (in-terms of sunspot activity on the solar disk) since November 7, 2014, and is currently at 15 daily events as of November 20, 2015. Through the majority of absent New England Winter's of the 1990's, the Sun was averaging 40-100 daily events, throwing back a moderate to high frequency of ultraviolet (UV) rays on-the-Earth. The higher frequency of ultraviolet (UV) rays acts to deplete ozone and in-return allows for pronounced cooling of the pole's stratosphere, with the Polar Vortex (PV) almost never splitting to influence middle latitudes of-the-Earth. Strongly taking into consideration current solar activity, lends hand to the highly cyclical 9-11 year (Schwabe) sunspot cycle, that we are indeed entering a solar minimum. The emerging sleep of-the-Sun will soon encourage pronounced warming of the pole's stratosphere due to increased ozone, * as this warming pushes down through the troposphere and eventual stratosphere, the PV will in-turn react and SPLIT, the pole will moderate. As the split PV drops south in-latitude, a reaction-to-action, ejecting the Arctic Oscillation (AO) North Atlantic Oscillation (NAO) into a pronounced negative phase. This will be the said driver of the 500-millibar Height Pattern over the Northern Hemisphere during the coming 2015/16 Winter season, NOT El Niño.
2. El Niño - the above said factors will tend to encourage an unusually stronger than normal or *enhanced* sub-tropical jet-stream, that will as-a-result of location, be a high moisture source to interact with the Polar jet-stream. This will be, an enhancer, encouraging a moderate to strong probability of Nor'Easter's.
When will this change influence New England?
While we have experienced a gradual step-down since mid November, there are key signals that will indicate CHANGE
A strong low pressure system tracking through the eastern Great Lakes region, producing rainfall in New England, around the week of November 29th may be the mechanism that encourages a significant pattern change. 
Therefore, December 5-12th is the time period of high volatility.

9-11 YEAR SUNSPOT CYCLE PROVES THREATENING FOR NEW ENGLAND (NE)!

Originally prepared: February 10, 2015 (Facebook timeline-post) 
The 2014/15 season is-the-true beginning of-a-cycle... supporting the RETURN OF classic OLD-FASHIONED-WINTER's in NEW ENGLAND! On January 14, 2015, I had posted that all-the-elements would (have the-potential-to) come together... with the return of the old fashioned New England winter, as experienced through most-of-the 1950's, 1960's, & 70's. As we realized the "cold", but had yet to observe a true snowstorm (Nor'Easter). Since-that-post, Boston has recorded it's snowiest 7-day period in-history (during late January 2015), and Hartford, CT. is presently averaging around 8-10°F below normal for the month-of-February. While there are various forms of long range weather guidance, such as NOAA's CFS forecast model... nature itself has already provided us with strong clues. These clues rest with understanding of-the-Sun's 9-11 year sunspot cycle, known as the Schwabe Cycle, which averages to be exactly 10.66 years. Sunspots are temporary dark spots located on the photosphere of-the-Sun, that significantly reduces the temperature within the darkened spot, in-contrast to the outer surrounding of the solar disk. However, the influences go-far-beyond the solar disk through the release of ultraviolet (UV) rays. UV rays (due to highly active "charged" sunspots) fall back on-the-Earth, which has a direct poleward effect. The higher frequency of UV rays acts to "cool" the pole's stratosphere, as the Polar Vortex (PV) remains over-the-Arctic... thus NOT SPLITTING, dropping south, to influence middle latitudes of-the-Earth. During the period of a Solar Maximum, is when this activity peaks... the Winter of 2011/12 was a Solar Maximum. However, we are now heading toward a Solar Minimum (the five-year-period between a solar maximum), which allows for a reverse effect... due to virtually no sunspot activity on the solar disk. In return, the pole's stratosphere "warms", encouraging "Blocking High Pressure" in northern latitudes as the Polar Vortex (PV) SPLITS, becoming significantly displaced from the pole as it drops south in-latitude (*has occurred during this 2014/15 Winter season). Of extreme interest, the sun will truly enter a Solar Minimum around the 2015/16 Winter season, and have strong probability to-be-deep within a solar minimum during the 2016/17, 2017/18, 2018/19, 2019/20, & 2020/21 Winter seasons... following this highly cyclical cycle!
