.: Why we do it! :.
Darwin Storms the website, is a journey
through the most thunderstorm prone area in the country. Compressed into four
months, lightning rates are comparable to other places around that globe that
have thunderstorm days throughout their whole year. Nowhere else in Australia
has the rate of storms, and perhaps severe storms. With a Bureau of Meteorology
estimated 50 Severe Thunderstorms Per Year in Darwin and its immediate
surrounds, this represents more severe storms than even thunderstorms alone in
most other parts of the country. Darwin is a great place to photograph,
experience and learn about weather. In a relaxed city that has been destroyed
by weather events 4 times, the city is new, vibrant, and according to the
Australian Bureau of Statistics, the most cosmopolitan city in Australia.
Cafes, palm trees, thick patches of monsoonal rainforest and a sense of local
pride is what you can expect to see on a visit to this remote, but modern brand
new city.
Tropical regions throughout the globe are seen to adhere to a general
tropical climatologically distinguishable pattern with storms. Good
lightning rates, minimal severe thunderstorm events, low steering winds
and no hail. But Darwin is a very different place, no other tropical
region in Australia matches its storm numbers, nor any city and its
immediate surrounds its severe storm numbers. Darwin is perfectly located
on the coast where, during the summer months, an inland desert and its
strong South Easterly airstream collide with a tropical Asian monsoonal
North Westerly flow. The combination of these events and many more lead
to the area being the most ideal place in the country for thunderstorm
events.
During the Summer months, hot areas of land over far Northern Australia
spin up as Heat Lows, Vast areas of low pressure, essential in drawing in
moist air from the NW towards Asia. For a period of this time, the well
established Strong South East flow from the inland desert of the Northern
Territory is still alive and kicking. The result is perfect. Squall
lines forming inland from the collision of air masses, wide scale
convergence and local convection trigger monster sized storms and start
their journey towards the city, pushed by those very strong South Easterly
dry winds. Lightning rates seldom seen elsewhere in Australia accompany
these beasts, quite often along with winds of over 120km/hr. Hail is
usually seen a few times every storm season inland from Darwin, a
remarkable event given the latitude
Of
Darwin's 100+ thunder-days, only an estimated 50 of them being severe each
season, means that all in all, if you don't catch a severe storm, you are
bound to see something. For a good part there are plenty of storms that
do little else than cool the place down, drop a few mm, and collapse on
themselves from light steering winds. Conditions change daily and keeping
an eye on the upper atmosphere is essential for the timing of your
interludes with the beasts of the Top End. The average speed for squall
lines entering the city area from the SE is usually between 20km and 75km
per hour. During the monsoon season, NW squalls (a totally different
variety of storms) usually sweep in at between 50km and 110km per hour.
