本文主要讲述的是降雨的研究，已经确定，在春季降雨期间，整个澳大利亚东南部地区的主要后果将经历一个显著的下降(Ummenhofer et al.， 2011)。这意味着降雨实例的数量、降雨持续时间以及降雨水量(以英寸为单位)将会因这一趋势而减少。第二个后果是碘化物事件导致的温度升高。已经确定的是，虽然IOD事件并不是在澳大利亚发生的所有极端天气事件中都存在，但大多数极端天气事件是由IOD引起的热量积累造成的(Ummenhofer et al.， 2009)。本篇美国酒店管理论文代写文章由美国论文通AssignmentPass辅导网整理，供大家参考阅读。
It has been identified that the primary consequence across the south east Australia regions will experience a significant decline within the spring rainfall (Ummenhofer et al., 2011). This implies that the number of rainfall instances, duration of rainfall along with the amount of rain water in terms of inches will be reduced and decreased due to the trends. The second consequence is the increase in the temperature due to the event of IOD. It has been established that while the events of IOD are not present in all the occurrences of extreme weather that takes place across Australia, majority of the extreme weather instances results from the accumulation of heat that is caused by IOD (Ummenhofer et al., 2009).
Therefore, it can be considered that the IOD trends in particular affect the rainfall related risks across Australia (Ummenhofer et al., 2017). The findings that the trend will continue to reduce the rainfall till next 10 decades will pose major risks of adverse and extreme weather conditions.
The third consequence is the most pressing since it is surfaced that the IOD enables the long term trend of drying within the warming climate. Hence, the intensity and the impact of the heat will continue to become more severe (Ashok et al., 2003). Therefore, it has been established from the research that the change in IOD trends towards increased drying of the areas poses the risks of extreme weather conditions and climate to the south east Australia. It has been found that these risks extend to all the nations that are surrounding Australia (Cai et al., 2014). Hence, the future extreme events such as the coral reef death, reduced rainfall, increased risks of drought and bushfires will continue to become more intense.
It has been identified from the above discussion and analysis that the phenomenon of Indian Ocean Dipole plays a central role in causing extreme weather conditions across south east Australia (Cai et al., 2013). It was surfaced from research that the El Nino contributes to the weather changes and results in the extreme events. Therefore, when the Dipole reaches a positive phase along with El Nino, the heat and deterioration of the weather conditions are impacted by the compounded effect (Cai et al., 2009).
