There were “untoward seasons” in 1859 and 1860. Motivated by the public’s increasing interest in the weather, Stephen Martin Saxby probed the subject. He began to develop a lunar theory for the weather. Through the pages of the “Nautical Magazine”, Saxby offered his developing lunar theory. In September 1861, he announced that November 2 through 5, 1861 would probably be a period of unusual atmospheric disturbance and that November 14, 1861 was especially dangerous for a cyclone to pass over Britain. A “heavy gale” came on November 2nd, and on the 14th a hurricane swept over London. As for the experts of the time, they had erroneously predicted moderate weather for November 14th. 
Early on in his investigations, Saxby had sent a letter to the Nautical Magazine which was published in its January 1860 issue. His tentative theory was that the moon never crosses the equator without there being a simultaneous disturbance of the barometer or thermometer, or both. “Such changes most commonly are accompanied either by strong winds, gales, sudden frost, sudden thaw, sudden calms, or other certain interruptions of the weather, according to the season.” 
Were these “strong winds” in other words the “straight line winds” we have been hearing about lately? Otherwise called derechos, the straight line winds are associated with bands of rapidly moving showers or thunderstorms. A derecho can produce destruction similar to that of a tornado. The damage typically occurs in one direction along a relatively straight path. As a result, the term “straight-line wind damage” sometimes is used to describe derecho damage. By definition, if the swath of wind damage extends for more than 240 miles, includes wind gusts of at least 58 mph along most of its length, and several, well-separated 75 mph or greater gusts, then the event may be classified as a derecho. 
In a scientific paper dated November 25, 2013, “Grand Minimum Of The Total Solar Irradiance Leads To The Little Ice Age”, Habibullo Abdussamatov does a fine job explaining his theory about solar activity and its influence on the weather. Yet the learnéd Abdussamatov does not consider lunar influence on the weather. (Background: Curséd, Damnable Cold Expected, Ersjdamoo’s Blog, November 23, 2014.)
Stephen Martin Saxby noticed that the occurrence of “most violent winds” routinely happened two days after the day of the moon’s crossing the equator. 
On October 23, 1859 the moon had passed the equator. The weather changed from “clear sky” and “fresh wind” to a calm, with a “dull” and very cold “drizzling rain.” Two days later “began that terrible and disastrous gale which for years will be remembered by seamen as the ‘Royal Charter Gale.'” 
The Royal Charter Storm of October 25 and 26, 1859 was considered to be the most severe storm to hit the Irish Sea in the 19th century, with a total death toll estimated at over 800. It takes its name from the Royal Charter ship (image), which was driven by the storm onto the east coast of Anglesey, Wales with the loss of over 450 lives. At the Mersey River a wind force of 28 pounds to the square foot was measured, more than ever previously recorded. 
High winds prevail at the time of the moon’s equinox, says Saxby. And extremely high winds happen two days after the day of the moon’s crossing the equator. 
On December 16, 1859 the moon crossed the equator. No sooner did the moon near the equator on the previous day than “the wind rapidly moderated, and at the precise time of the lunar equinox (if one may use that term with the moon), a dead calm set in, the intensity of the cold increased, and the wind, which had been blowing from the NNW for a few days, shifted around to SSE…” 
From what I can gather from Saxby’s work, these “lunar equinoxes” (not the same as solar equinoxes) happen at least once a month. They seem to occur sometime between the new moon and the full moon.
There can be a change in the electric tension of the air leading to atmospheric disturbance due to the influence of the moon’s position in its orbit.  Circa 1876, General A.J. Pleasonton also noticed the effect of electrical disturbances in the upper atmosphere. Pleasonton, like Habibullo Abdussamatov, focuses on the Sun’s weather influence. Saxby however focuses more on the Moon. (Background: Canopy Of Cold Descends, Ersjdamoo’s Blog, November 20, 2014.)
