What kind of weather forecasting software is easy to use and has high accuracy?

As the saying goes, the accuracy of weather forecast cannot reach 100%. Because the weather system is nonlinear at first, according to chaos theory, the weather forecast can't be 100% accurate. Moreover, the ground meteorological observation stations are widely spaced and unevenly distributed, and some small and medium-scale weather phenomena, such as thunderstorms, tornadoes and hail, often become "fish that slip through the net". At the same time, the digital weather forecast approximately represents the evolution law of the atmosphere as a set of mathematical equations. By solving the equations, the forecast of future weather or climate conditions can be obtained, and the initial value error and calculation error will also be enlarged with the passage of time. In addition, global climate change increases the difficulty of weather forecasting, and the probability and frequency of extreme weather events are increasing, which requires forecasting experts to further understand and understand the weather characteristics and climate change laws, and constantly discover, summarize and supplement new forecasting experiences.
