Long rainy summer is coming – News online

It will rain more than usual, all over the east coast

If you were wondering why we have such a rainy spring in Australia, with temperatures mostly below the average for this time of year, the answer arrived on Tuesday, from the best climate and weather experts in the country.

The Bureau of Meteorology (BOM) has officially announced that La Ninja has arrived on the coast of Australia, a climatic phenomenon characteristic of the southern hemisphere, which brings with it higher amounts of precipitation, slightly lower temperatures, storms and increased humidity.

This confirmed the forecast given by BOM at the beginning of October, with one important correction – La Ninja will probably stay until the very end of the summer, and it is not excluded that it will be transferred to the beginning of autumn.

What does La Ninja mean for Australia?

First, get ready for a long, rainy summer. In the coming months, we will not see beautiful, sunny and extremely warm days.

On the one hand, it is not so bad because we will certainly avoid the season of large forest fires, but on the contrary, we can be hit by a large number of cyclones, frequent storms, and maybe floods. Especially since the unusually wet winter and spring are behind us.

La Ninja will primarily hit the east and north coasts of Australia, and there will be increased rainfall in the central parts of the country. According to meteorologists, it will still be weaker than last summer, since this is one of the rare cases when La Ninja happens for two years in a row.

The same phenomenon struck Australia during the summer of 2010-2011. and 2011-2012, with the proviso that the impact of this phenomenon on weather conditions was far stronger than it will be this season.

– We had the last strong La Ninja in the period 2010-2012. It was then that the wettest two-year period in the history of Australia was recorded, which brought great floods in many parts of the country. It will be significantly weaker this year, we expect even with less bad weather than it brought last summer – says the head of the operational climate service at BOM, Andrew Watkins.
However, the problem is that the country is already saturated with water, and many dams on rivers are already at the level of maximum capacity, so new heavy rainfall could lead to their flooding and potentially dangerous situations in some parts of Australia.

How is La Ninja created?

According to BOM, La Ninja brings continuous cooling of the eastern part of the Pacific Ocean during September and October.

When cold water from the east, carried by strong winds, meets hot water on the surface of the oceans in the north and northeast of Australia, there is increased evaporation which creates a large mass of rain clouds. This leads to heavy rainfall, and often to storms and cyclones in this part of the continent.

However, although it generally brings lower temperatures, the humidity of the air system of high atmospheric pressure, which moves slowly, enables the creation of occasional heat waves. So this summer, it is not excluded that despite the larger amounts of rain, we also have extremely warm periods.

BOM will release an official long-term weather forecast for the entire continent today, but what is already known is that the entire east coast, especially the eastern parts of Queensland, New South Wales and Victoria, will receive over 60 percent more precipitation than usual in the summer. . Anyone living from Cairns to Melbourne can prepare for a long, rainy summer.

Possible third La Ninja ?!

Meteorologists say that La Ninja rarely happens for two years in a row, but they do not rule out the possibility that it will happen for the third time, at the end of 2022! Namely, Australia was hit by La Ninja for three consecutive years from 1998 to 2000. Also, climate change and global warming contribute to their more frequent occurrence.
Scientists believe that if the climate continues to change, La Ninja could “come” an average of eight to nine times a century, instead of the current five to six. If we know that it has happened four times in 20 years of this century, it will not be difficult to surpass that average.

Storms by the end of the week

The effect of La Ninja is already being felt throughout Eastern Australia, which has been affected by showers, cloudy and humid weather for days. The forecast for the rest of this week is bad, as meteorologists say that heavy thunderstorms, which began to spread from South Australia to the interior of New South Wales and Queensland, will cover most of Victoria today.

The storms will hit Queensland and Victoria first, and New South Wales on Saturday. Of particular concern is the areas of East Gipsland and the northwestern slope of the NSW, where the largest amounts of rain are expected, even up to 100 millimeters.

“Spared” Western Australia

Forecasters claim that “half of Australia” will be affected by frequent rains this summer, and gray clouds should only bypass Western Australia. La Ninja does not affect this coast of Australia, since the influence of the Indian Ocean dominates in the west.

Perth and the surrounding area have had a lot of precipitation in recent weeks, but it is not expected that there will be precipitation during the summer, as is usual for this part of the country.
