![]() ![]() Generally speaking, weather in spring and summer such as fog, tropical cyclone and severe convective weather is more changeable, resulting in higher uncertainty of forecast. The accuracy and error of forecast also vary for different weather systems in different seasons.The errors of PSR forecast in the next one to six days are within around 10% and those in seven to nine days are within around 20%. For forecast elements in "9-day Weather Forecast" other than PSR, the average accuracy for the next one to three days, four to seven days, and eight to nine days are about 90%, 85% and 80% respectively. The accuracy of forecast generally decreases while the error generally increases with forecast period.
