In Australia, there are a lot of Irelands, in which Tiwi Irelands are one of them. These
Irelands are the part of Northern Territory. The distance of these Irelands is 80 km to the
north of Darwin and Adjoining the Timor Sea. The combined area of 8,320 square km.
Tiwi Island consists of two Islands. Melville and Bathurst. The people who are living
there are famous for their stunning artwork, passion for football, vibrant textile, and
traditional lifestyle.
A thunderstorm develops in the Tiwi Ireland from September to March every afternoon
in Northern Australia. Meteorologist refers to it as Hector due to its regularity. This
thundercloud called cumulonimbus mostly appears at 3 PM, and according to some
experts, It is so punctual alarm can be set. Another name of Hector is Hector the
Convector, this storm got this name after World War II when the mariners and pilots
used the thunderclouds for navigation purposes. Hector can access immense heights,
some 20 kilometers tall, and it can be seen from Darwin, a distance of 100 kilometers.

The shape, size, and location of Tiwi Island make them an amazing place for the
development of Hector. According to Ben Domensino meteorologist with the
collaboration of a DTN company named Weather zone. The amazing view of the sea
from all sides of Ireland. The cold wind, which is moisture from the sea, needs to go
somewhere when they disturb. The temperature of the air becomes cool when it rises,
and the result of the rising air is water vapors condense and converts to liquid.
Shepherd said that it is common in wet weather where the sea air plays the role
of a lifting trigger, and this weather is a tropical atmosphere. The weather from
September to December is called the build-up session and Hector is commonly found
during the summer. If the temperature increases, it shifts into April. During the late dry
session (In September), winds extending their size from the subtropical ridge to the
south will defeat thunderstorm activity more than in the Northern Territory. And before
the wet session in October and November, the prominent feature of leaving Hector is
the isolated feature on the Darwin skyline. This was the point of view of Lan Shepherd,
who was the senior meteorologist at the Australian Bureau of Meteorology.
The weather of Tiwi Ireland is unexpected and its tropical atmosphere is always
prepared for the formation of a thunderstorm during the wet season when the breeze of
the sea converges and provides the trigger, said, Shepherd.
Hector is also happening during the warm months which is called build-up season from
September to December. Hector is also common in the rainy season from January to
March. Sometimes Hector appears in April if the temperature of the wind is warm
enough.
The one condition when Hector does not appear is when there is a continuous
westerly monsoonal flow.
The cloudy weather and the westerly winds connected with a serious
monsoon tends to suppress sea breezes on all the Irelands, decreasing the
likelihood of Hector forming regularly. According to Shepherd, “An active
monsoon also generates regular showers and thunderstorms which move
rapidly across the islands from west to east in the relatively cool maritime
airstream."
The best time or condition for the hector to occur is when the sky is clear with
a very light wind, this is not only suitable for strong solar heating, and also the
source of daytime sea breezes. In the months of winter from May to August.
There is no chance of Hector and it lowers the strength of the sea breezes.
