台风最大风速是最大风速半径、局部最大气压梯度和最大风速处的空气密度的函数。卫星图片和飞机侦察可以准确地确定最大风速半径,但其最大风速一般很难得到准确的数值。美、日和印度等国许多学者,根据理论上的台风最大风速V_m与台风中心海平面最低气压P_0之间的关系: The maximum typhoon wind speed is a function of the maximum wind speed radius, the local maximum pressure gradient and the air density at the maximum wind speed. Satellite images and aircraft reconnaissance can accurately determine the maximum wind speed radius, but the maximum wind speed is generally difficult to get accurate values. According to the theoretical relationship between the maximum typhoon wind velocity V_m and the lowest typhoon P_0 at the typhoon center, many scholars in the United States, Japan, India and other countries:
