Three planets, each resonating on a different vibratory rate, are used for astrological weather charts - the Sun, Mercury and the Moon.

The Sun. The Temperature Chart.
This chart is erected for the moment when the Sun (hot by nature) crosses over into the four seasonal quadrants of the year - the zodiacal signs Aries, Cancer, Libra and Capricorn

Mercury. The Air Movement Chart.
This chart is erected for the moment when Mercury (airy by nature) moves into a new zodiacal sign.

The Moon. The Moisture Chart.
This chart is erected for the moment when the Moon (watery by nature) dividing like the Sun, into four quadrants, moves to New Moon, First Quarter, Full Moon and Last Quarter.

These three weather charts are the same all over the world.

Such charts, erected for Greenwich Time, are the same all over the world. But when each is erected with the locale of a specific geographical latitude and longitude in mind, each chart will display not only its unique astrological features, but the astrological influence on that region, be it the middle of a desert, the heart of a tropical jungle or a great metropolitan centre.
