The Australian climate has been super weird this week. Here’s why.

Australia desperately needs the rain, but not so.

Area choked with smoke earlier this month has been throwing Hail the size of Golf over the past few days, smashing cars and Windows, literally .

People around the world have been hoping the Australian will soon get enough rain to break the long and trying drought. Unprecedented forest fires have been ravaging the country for months, burning approximately, destroyed more than 2500 homes and killed 30 people. Experts estimate that more than have died, the recovery is expected to take decades.

The recent arrival of rain, so a welcome relief. Although it is not off the carpet of the Australian people the hope, in fact, rain helps to put out or contain a fire.

However, severe storms also created new, different problems, from floods in Queensland, a devastating hail storm in Canberra. These conditions are in stark contrast to the forest fires and dry dust storms to blow into these same countries, leaving many Australians don’t know what the hell is going on.

But according to the Australian Bureau of Meteorology Diana Eadie, the rain at least is quite normal.

“(This)is not unusual to experience such a storm broke out, at this time of year in Australia,”Eadie told Mashable. “That is to say, the sudden collapse of the dry climate driven back to more typical weather has felt, to many people, and not sudden.”

Basically, Australia has not seen rain for so long suddenly returns to the normal state has been flooded.

Why is Australia the weather is so dry?

“Australia is currently the severe weather season, which is characterized by severe storms, fire, flood and tropical cyclone activity,”said Eadie.

According to her, Australia recently the weather is affected by global warming and patterns in the surrounding ocean and atmosphere. “These climate drivers act not only to strengthen the fire danger, but also suppressed thunderstorm activity, we generally expect the impact of Eastern Australia in spring and summer.”


These patterns are the changing temperature in the Indian Ocean, known. Supervision of the division through three stages of positive, negative and neutral—with Australia just experienced a”very strong and long-term”positive phase.

In an active supervision of the Director of the division, a weak westerly wind warm water allow to move to the Western Indian Ocean, from Australia. At the same time, cold water rises from the depths of the Middle East, in Australia’s North-West Coast. This means less moisture and fewer clouds the atmosphere around Australia, affecting the track of weather systems approaching from the West.

The end result is more heat, more dry conditions in the Central and South-Eastern Australia, is conducive to forest fires.


While a positive IOD is one of the main factors that influence Australia’s weather, Eadie also noted that it intensifies the effects. This refers to the North or South of the transfer of the strong westerly wind it around the Earth in southern Australia.

Negative SAM from late October to late December wind shift too far North. This caused them to destroy the entire continent the hot, dusty Central, lost to the tide by the time they reach the East coast and cause little rainfall.

The IOD and SAM are a normal part of the Australian weather cycle. What is not normal, the condition is also being affected by climate change. Australia’s drought becomes longer, more and more frequent as the global temperature trend to rise, exacerbating the already hot like that fire season more and more extreme.

Why is Australia the weather became so wet?

Fortunately, both the IOD and Sam have returned to a more neutral phase, in the last few weeks. This makes the East wind-water coral and Tasman Seas of the East coast of Australia in the tropics.

“Recently, a complex low pressure system moving through the Southeast of Australia and tapping into this moisture source to cause the severe storm activity we saw in Melbourne and Canberra in the past days,”said Eadie.

A low pressure system is a region, where the atmospheric pressure is lower than the surrounding areas. This will cause the wind toward the system, rising and forming rain clouds. This system becomes complex when they have more than one low pressure center.

Of course, at the same time, the rain may be normal, the size of the hail is small. Speaking to ABC News, Dr. Joshua Soderholm attributed to the huge ball of ice form a super storm—one of the most common and most severe types of thunderstorms.

“Super-cell is special because they have a very broad, strong and sustained updraft, so you can imagine the hail of growth conditions applicable to the Hail,”said Soderholm.

Rotating updraft found in the super-cell”to allow them to become more intense and last longer, which allows them to in turn produce more hail.”

Do forest fires have anything off the storm?

Eadie acknowledged that forest fires can create their own weather systems, forming clouds of space-time hot gas and fine particles to rise to the point of condensation. They even can produce a thunderstorm in extreme cases, exacerbated the fire danger with the Lightning and the Gale attack.

“However, severe storms have been Eastern Australia recently are not directly related to the forest fires,”Eadie noted. It seems Australia just lucky.

Severe storms are possible behind the March, but until then Australia is recommended to support more wild weather. While New South Wales experienced the temperature exceeds 40 degrees Celsius(104 degrees Fahrenheit)on Thursday, severe storms forecasting, in order to combat the country’s Northeast on Friday and the weekend, might bring”large hail, damaging winds, and locally heavy fall.”

Although Australia’s wild weather may seem like the end of the world,it is largely dramatic contrast that makes it feel that way-despite the size of the Hail there is no denying the unusual storm of rain isn’t a harbinger of doom. To forest fires and drought, however, may be another story.
