Vernal equinox and weather

On March 21st at 1.30am NZ time the sun crosses the east/west line in its daily risings, heading northwards. In the southern hemisphere the summer sun rises in the SW and slowly moves north, going from southernmost position Dec 22nd(summer solstice) to the northernmost point (winter solstice) June 21st. Halfway is when it crosses the equator, called 'equinox'(equal night) because on that day, the number of daylight hours equals the number of darkness hours. Equinox marks the beginning of autumn, which is why it is then that we change out of daylight saving. What does this indicate weatherwise? The equinox is only about the sun. If the sun controlled the weather then the same weather should occur every equinox, right on March 21st. Of course we all know it does not.
The bad weather waits for the moon to get into position.Ý Readers of this ezine will be aware that New Moon and Moon-crossing-equator are two bad weather events, as is the Moon-at-southern-declination. On March 21st the moon will be just leaving the southern declination and Auckland will get light showers and light winds as a result. But I'm picking they will be slight compared to the rain a few days later on the 26th. The March New Moon always brings this double whammy. The March New Moon crosses the equator heading north on March 25th this year. But next year that same condition (March New Moon crossing equator heading north) occurs on March 14th and has to wait till March 31st in 2003. Last year the same condition occurred earlier and later, on March 6th and April 4th. What they call "equinoctial gales" will occur around those days, and not ever on March 21st unless the March New Moon and vernal equinox(Sun) occur on the same day.
The mechanics of the situation are that when the sun is on the equator and the New moon is also, a three-fold combined extra gravitational effect occurs. They did occur on the same day, in 1966, with devastating gales and floods a week later in Auckland, Nelson and central North Island districts. In 1955 the New Moon plus equator-crossing PLUS the moon's perigee coincided with the vernal equinox. And..did THAT bring some weather! There was a raging cyclone in Fiji and Queensland, and a blizzard in New York. In Brisbane three inches of rain fell in 20 minutes.
So this year March 25th-27th should see widespread rain, here and in most parts of Australia. Blenheim and Nelson will get some on the 20th, but Blenheim more on the 26th. New Plymouth sees showers only on the 26th. Timaru, closer to the southern declination, should get more rain around the 20th/21st.

Crescent holding water?Ý

Some readers will be familiar with ancient folklore which says when the crescent moon is on its back, it is "holding water". Is this true, and therefore some guide to bad weather coming? The answer is, well yes, partly.. At around 6am on 20th March and on the 20th April above the east the crescent-on-its-back moon can be seen. It is a few days before the New moon. There will be some rain in a couple of days BECAUSE of the New Moon, which can be relied on to serve up rain. Look again in the sky around 8pm in the evening of 24th July as the moon sets in the NW. Once again you'll see the crescent on her back. It is close to 1st quarter now, and moving away from New Moon. It means rain, yes, but this time it is going, but only because these two opposite crescents are on either side of that delinquent weather factor - the New Moon.

Vernal equinox event

If anyone wants to see part of the Ancient Marker System at work in Auckland, do join a small group of us around 6.30am on the summit of Mt Albert at sunrise on the morning of Tuesday 20st, when the rising sun will appear to rise from the top of the ancient heel stone (by the trig station) at about 7.10am. The thin crescent moon lying on its back will sit above the east pointing to the rising sun. It will be a remarkable sight if the sky is clear. Unfortunately it's a day early but I'm picking that the next day, which is the true equinox, may be too cloudy. That (Tuesday) evening we will again assemble on Stockade Hill in Howick, where once a stone circle stood, to watch the equinox sun disappear into the man-made "V" that was cut into Mt Wellington for this very sighting purpose at least 2,000 years ago. Some folk will be on Mangere mountain, where there are more ancient equinox markers. Time of sunset over Auckland is around 7.20pm.
Few Aucklanders realize that our city was inhabited thousands of years ago, as proven by these many equinox structures. Are the media interested? Nah. We tried to interest them last year, but only the Howick Times printed anything.
If you could get along to at least one of these events it would be nice for some of us to meet - and bring the kids!

Hi Ken,
My wife and I, and our pet rabbit really appreciate your web site.Ý Your pages on Ozone and Global Warming were most educational - amazing what we will take on and believe without asking any questions! It certainly allows for a bit more relaxation in life and an 'unhooking' out of the mass hysteria.Ý Very reminiscent of the whole Y2K panic isn't it. Anyway, thank you for your alternative and humourous views on this.
Take care
Himiona and Anihera
and Mihinoa Rabbit


Hi Ken
I'm Matt I'm a greenkeeper in Swanson. I listen to Mikey Havoc in the mornings and listen to you every week. You are a legend and don't let anyone tell you different. Thank you so much. Your info helps us in ways that you never only could dream of.
From Greenkeeper Matty


Ken
Every prediction I've heard of yours about fishing for the weekends has been spot on, thanks heaps, I was wondering what your prediction for this weekend is. It would be excellent to see a weekly fishing prediction on your website.
thank you
Steven
