Weather fire in Australia

At the same time of the development of COVID-19 epidemic, mountain fires in Australia are constantly happening, and the jungle fire in Fraser Island of Australia is approaching the seaside town, which makes people start to think about why mountain fires are frequent in Australia.

First of all, climate change has led to an increase in high fire danger weather, and forest fires have been erupting all over the world. Frequent forest fires have seriously damaged the ecological environment, destroyed the stable cycle of the ecosystem, and even caused permanent damage, which seriously threatened the global ecological security. Especially under the influence of severe weather such as high temperature, drought and strong wind, the fire is improperly handled and quickly out of control, which threatens the safety of life and property of the city and people and is not conducive to social development. Harmony and stability.

Secondly, Australia has a hot and dry climate, flat terrain and few mountains. Eucalyptus is the main tree species, which is rich in oil. Affected by many factors, Australia is one of the countries with the most frequent forest fires in the world. El Nino phenomenon leads to more extreme weather. ? El Nino refers to the continuous abnormal warming in the central equatorial region and the eastern Pacific Ocean. The abnormal warming of Peru's cold current in the eastern South Pacific leads to the increase of temperature and precipitation in Peru's coastal areas, which affects the atmospheric circulation and leads to the decrease of precipitation in eastern Australia. It is located in the western part of the South Pacific, which leads to high temperature and dry weather and increases the risk of forest fires.

Finally, tropical cyclones lead to an increase in bad weather. Tropical cyclone is a strong and deep tropical weather system that occurs on the surface of tropical or subtropical oceans. Tropical cyclones produced in the Indian Ocean and the South Pacific are called cyclone storms. Tropical cyclones in the waters off Australia? Blake. Reach level 9. It moves east and then south at the speed of 10 km/h, and its strength gradually increases. Claudia, a cyclone off the coast of Australia, intensified into a tropical cyclone of level 3, mainly occurring in the northwest of Australia, with the maximum wind speed 186 m/s.
