In Summer Solstice, due to strong heat absorption by ground and air convection, thunder showers that come and go quickly occur a lot between noon and dusk. Because rainfalls during this period are limited to a low range, people usually call them "raining within one field."
A famous poet of the Tang Dynasty (618-907), Liu Yuxi, described this kind of weather in one of his poems "the eastern sky is sunny while the western is rainy; it is thought to be rainy but the sun is still in the sky."
