What is the regional rainstorm situation in Beijing, Tianjin and Hebei in the next three days?

On June 20th, affected by the vortex moving eastward slowly, there will be a regional rainstorm in Beijing-Tianjin-Hebei region from February to 24th. The rainfall has the characteristics of long duration, wide influence range, large accumulated rainfall and strong convective weather.

In response to the online rumor that "the biggest cold vortex rainstorm in six years will come to Beijing, Tianjin and Hebei", Beijing meteorologists responded that under the influence of the vortex weather system, the water vapor convergence is obvious and the upward movement is strong. In addition, the vortex moves slowly and the precipitation lasts for a long time, which is easy to form rainstorm weather.

Guo, chief forecaster of Beijing Meteorological Bureau, said that in the early stage of rainfall, weak cold air and warm and humid air flow meet obviously, and the atmospheric convection is strong, accompanied by lightning, short-term strong wind and hail, and the short-term rain intensity is strong; In the middle and late stage, due to the influence of vortex, the temperature of the whole atmosphere drops, the convection weakens and the rain is relatively stable.

Among them, the strongest rainfall occurred from the night of 2 1 day to the 23rd, and the cumulative rainfall level in central and northern Hebei, Beijing, Tianjin and other places can reach heavy rain to heavy rain, local heavy rain and short-term heavy rainfall.

From the afternoon of February/Kloc-0 to the night in Beijing, there are thunderstorms in most areas, mainly moderate to moderate rain, with uneven rainfall distribution, strong local short-term rain, accompanied by short-term strong wind or hail. The strongest rainfall period occurred from day to night on the 22nd. There will still be showers or thunderstorms from 23rd to 24th. In most areas, the cumulative rainfall level can reach heavy rain to rainstorm (40-80mm), with heavy rain in the western piedmont and northeast, local heavy rain (100-150mm), and the maximum hourly rainfall intensity is 30-50mm.

Meteorologists suggest that heavy rainfall will lead to road water accumulation in low-lying areas and some road sections, which will have a great impact on urban traffic on the morning and evening of the 22nd. Stay away from dangerous areas such as mountains, rivers, reservoirs, tourist attractions and construction sites during rainfall. Pay attention to prevent geological disasters such as floods, flash floods, mudslides, landslides and collapses in small and medium-sized rivers that may be induced by heavy rainfall in mountainous areas. In addition, continuous rainfall will affect the harvesting and drying of winter wheat, reminding us to seize the time to harvest and dry.
