Monsoonal Cloud Movements
over South East Asia
In attempting to familiarize
myself with weather patterns and cloud movements over China in
July I've created a series of animations to visualize it more
easily. Cloud photos are courtesy of the Australian Bureau of
Meteorology. This page began life as a review and planning tool.
It was not originally intended for public consumption. As such
the opinions expressed are those of Joe Cali and not the Australian
Bureau of meteorology nor the Australian National University,
Research School of Earth Sciences. It is however the readers
responsibility to review all opinions on the weather and form
their own observing strategy and I take no responsibilty for
missed opportunities that result from reading opinions expressed
on this page.
Warning, the animations
you are about to open are very large. The total content of the
page is more than 15MB!

photo or video and plenty of time left over to enjoy the spectacle............more
A Discount Eclipse
The cost of seeing a solar eclipse
is usually prohibitive but the 2009 event is different. Shanghai
is a major air hub. Lot's of cheap flights are available particularly
with the current recession.
Accommodation to suit any budget
is readily available in downtown Shanghai.
On July 22nd, downtown Shanghai
experiences just over five minutes of totality.
Spend a little more - grab a taxi
and head south just for the morning. The closer you can get to
the coast on the river the clearer the air will be.
A lot of people are heading to
Hangzhou - a tourist city set around a lake to enjoy 5m20s of
totality. You can catch a bus to Hangzhou from Shanghai Pudong
airport. Hangzhou has a huge number of hotels and apartments.
So if the price has put you off
in the past. You're never been sure if it's worth the money.
Well, here's your chance to get hooked and be poor for ever more.

Eclipse Timing with your iPod
If, like me, you lose track of time during totality, maybe this
can help. During longer totalities > 3 mins I'll check a clock
a couple of times only to find that only 30s or a minute has
passed. So I relax then suddenly the diamond ring appears. I've
come to the conclusion that the Hubble Constant varies wildly
during totality causing the passage of time to feel uneven -
or maybe I just get distracted.
Apple Macs come with
a suite of software included in the price. One of these programs
is called Garage band. At first glance, I dismissed it as a piece
of junk until I saw a segment on TV about the program annd realized
that it had hidden talents. I first used it to compose a handful
of salsa songs. I added some narration and put together a salsa
rhythm tutorial CD for our dance school (http://www.salsambada.com.au).
The advantage of using Garage Band is that music generated using
this program can be freely distributed without breaching any
copyright provided you don't import copyright material into the
program. Garage Band comes with a library of riffs and beats
and an array of synthetic instruments you can play yourself using
a cheap USB keyboard. We make lots of copies of this CD and give
it to our beginner students for free to help them learn rhythm.
My latest project is
an eclipse-timing track. The track uses an eleven-minute count
down to the start of totality followed by a count up during totality.
The track starts 11 mins before totality. The diagram illustrates
the time signals and announcements. Each place on the time track
marked by a number is matched by some sort of announcement and
an electronically generated time pip on the track.
At -10 mins there is
a count in to help you to synchronize the track with real time
at your site. If you miss this, fast forward to the 9, 8 or 7min
markers. Each minute marker is preceded by two short pips in
the preceding 2 seconds.
