The high temperature events are frequently occurred due to global climate change, which is harmful to human existence, social and economic development, water resources and ecologic environment. The goal is to improve the ability of coping extreme weather events for the whole society and promote the sustainable development of national economy. Based on the self-organized critical and previous research, this paper explored the frequency-intensity distribution of temperature change satisfied Gutenberg-Richter power-law relation. Then, a numerical sandpile model with decay coefficient is constructed to reveal inherent dynamic mechanism of high temperature events based on the idea of sand model. The study on occurring mechanism, temporal evolution and inherent dynamic behavior of high temperature events, which could provide the scientific basis and important reference for effective establishing all kinds of emergency plan such as extreme weather disaster prevention, mitigation and relief.
