Timely rain in Australia can extinguish fires and quench thirst
The U.S. government said on the 11th that the recent heavy downpour in the east may pour out all the remaining fire fields in New South Wales, which was once critical, and thus end the forest fire crisis this weekend.
[Fire risk can be removed]Since September last year, forest fires have broken out in several states in southeast Australia, forming dozens of fire fields raging in many places.
Some experts believe that climate change has caused Australia to experience severe drought for three consecutive years, and last year’s unusually long dry season contributed to the spread of the fire.
Heavy rains and storms have recently swept through the scorching fire, the most populous state of New South Wales, bringing hope to the fire.
Heavy rains have extinguished two of the largest and longer-burning fires. State officials expect more rain this week to try to extinguish all 24 fires in the state, including four runaway fires.
The NSW Rural Fire Department said in a statement that if everything goes well, all fire fields will be brought under control.
We can hope to reach that goal, that is to say the fire is gone.
Reuters reports that the current expectations are very different from the violent fire in early January.
At that time, firefighters in NSW were battling about 150 fire fields and facing nearly 6,000 kilometers of fire.
At first, the fire raged in Victoria for more than 4 months, and the fire area was nearly 12 million tons, killing 33 people, carbonized an estimated 1 billion animals, destroying thousands of houses, and causing large-scale evacuation of local residents and tourists.
Reuters described the red sky as thick smoke, like the end of the world.
[Surprise]This long-awaited heavy rain is a surprise in advance.
The U.S. Meteorological Agency said in January that it would not be until at least March that it could hope to smash the rain that extinguished the fire.
In the state of Victoria adjacent to NSW, firefighters continued to fight with about 20 fire fields on the 11th, a number that was two-thirds lower than the 60 fire fields at the time.
The state of Victoria was also expected to have rainfall in the past few days. Although local officials did not expect heavy rain to pour the fire extinguishing area, it could at least dampen the fire.
State emergency department official Tim Wibusch told media reporters in Melbourne: This rain cannot extinguish forest fires, but it can limit the spread of fire or let firefighters control the fire in the near future.
In Queensland, after the heavy rain, only one area of fire was still burning.
In southern South Australia, nine more fire fields are burning.
Gary Calvert, mayor of Hawkesbury, New South Wales, said that everyone was relieved that the huge fire on the surrounding Gospers Hill had gone out.
We have been with the fire for 4 months and never dare to relax, because the fire changes with the wind at any time. For several weeks, we have packed our luggage and prepared to retreat at any time. He told a Reuters reporter that smoke and dust can also destroy you. WeThere is an urgent need for fresh air.
However, at the same time that the rain brought good news, it was also a double-edged sword.
The flood caused by the rain broke the power lines, causing about 60,000 homes in NSW to lose power on the 11th.
[Difficult drought conditions]Sometimes a timely rain can extinguish Australian forest fires, but researchers said on the 11th that in order to alleviate the drought that has lasted for several years, it requires rainfall volume and longer rainfall.
Queensland Mayor Tracey Dobby said that the rain is good news for everyone, but the drought is not over, our land has suffered severe water loss, and it has not been raining in some places for 3 years.It does not rain for 5 years, so it takes a long time to restore the humidity of the land.
Hydrologists believe that the heavy rain this 西安耍耍网 week is just the beginning, triggering floods and pouring forest fires, cities are accumulating water due to rainfall, and rural areas are still struggling with continuous drought.
Professor Ashish Sharma of the University of New South Wales said that heavy rain may create the illusion of urban residents, seeing hard surface water, triggering floods and property damage, but there is no rural area that still needs continuous rainfall to infiltrate dry ground, makingThe reservoir is filled with water.
During this round of rainfall, the water levels of some of the reservoirs around Sydney, the largest city, increased. However, in the towns that experienced drought in NSW, most of the rainwater flowed into the river, and the reservoir storage capacity increased only slightly.
An NSW water company employee said: Unfortunately, there is not enough rainfall.
After a hot early summer and continued recovery, the river basin was extremely dry.
Sharma and his team predict that climate change will lead to extreme conditions in the growing season, but still cannot continue to cause water loss caused by elevated temperatures.
I hope that people will incorporate vision and wisdom wisely. This extreme situation has become a reason for people to ignore the truth, instead of doing nothing.
