How Long Range Forecast Are Derived

How Long Range Forecast Are Derived

Long range weather forecasting techniques are hundreds of years old with the first known work on weather and the atmosphere by Aristotle, The Meteorolagica (384 BC to 322 BC).

The bulk of weather information, the influences, comes from our solar system planets, the Moon and the Sun.  Basically, the planets that move quickly around the Sun – Mercury, Venus and Mars – can align with each other and disturb the atmosphere.  Sunspot or solar flares activity that also permeates our atmosphere was discovered by RCA’s J. H. Nelson.  His book, Cosmic Patterns describes how the solar system planets interact.

The Moon carries air tides quickly as it travels around the Earth.  The air tides can be followed by observing the Moon’s monthly declination position from north to south of the equator.   The Moon’s position in longitude and latitude plus the position and speed of each object is needed in order to develop a forecast.  Since we know the date and time of each of the lunar phases we are able to calculate the necessary charts which are analyzed for weather information for anyplace or anytime in the future.

The Moon’s perigee has a significant effect on weather in various locations each month.  If there is a stormy forecast during a perigee period (about 3 days monthly) the storm is intensified.  Have you ever heard a TV weather forecaster mention the word ‘perigee’?  Probably not – I haven’t either here in New England.   Perigee is when the Moon is closest to earth and has a stronger gravitational effect such as higher and lower tides and stronger wind activity once a month.

Did you know that in ancient times, the astrologers were also the astronomers?  Today, modern science wants no part of astrology and who can blame them when their knowledge of astrology is limited to a Sun sign column and other misinformation.  What they don’t realize is that we live in a solar system where each of the bodies has light and that light comes to earth at various times and places.  The light is disturbed when the bodies aspect each other as proven by Mr. Nelson who is mentioned earlier in the article. No doubt many will dispute the existence of the light, but then, how else would we derive an accurate forecast?

Long range weather forecasting incorporates two systems of astronomical measurement. The astrological observation of how the planets via the ecliptic interact with each other to provide the information in the form of a chart or horoscope.   The measuring of the plant’s location north, south or on the equator is called declination, and is the second astronomical measurement.

In the western world, the most popular system of astrology is based on the seasons – tropical astrology.    For example, when the Sun climbs to the equator each spring, at the moment it crosses zero degrees of declination, is when we say the Sun is at zero degrees of the Zodiac sign Aries and it goes on from there.  Do not confuse western tropical astrology with Vedic (Hindu) astrology which measures the Sun and planets against the constellations and is another form of a measurement system.  And, there are other systems as well such as Chinese, Burmese, Sidereal and more.

Each system of astrology can be used to forecast weather; it is simply a matter of studying the objects and assessing the correlations.
