These days around the equinox have been a challenge to my initial theory of the BD Calendar. I have measured rains with the Moon in the various constellations, with by far more rain in the Root/Earth and Leaf/Water Constellations. But, at this time of year (Spring and Fall,) I found a contrary effect, perhaps due to the fast-changing day-lengths that the North and South temperate latitudes experienced these days (about 4 weeks each side of Sept.21)
Here it important to distinguish between AMOUNT of rains, and CHARACTERISTICS of the rain. By characteristics, I mean “sudden downpours,” Gusts,” and “Daytime vs. Night Rain.”
Seeing the fabulous weather maps, most accessible of the USA, such as http://www.lawrencevilleweather.com/dewpoints.htm, makes this all the more graphic. For example, just as we left Flower/Air for Leaf/Water at 0800 UTC, 5 Sept., the contintal USA was nearly clear of clouds. After just 14 hours in Leaf/Water the rains were spread over much of the map.
That aside, the nature of the rains in the various periods retain characteristics: Daytime rains in Leaf/Water constellations, often as a surprise shower. Night rain in Root/Earth as a continuous drizzle. Barometric pressure increasing during the Flower/Air period. Rains in Fruit/Fire arriving powerfully after a long threatening blow.
