Shijiazhuang dust weather analysis and forecasting
Based on the historical data from the 17 counties, analysis was conducted from the aspects of time and spatial distribution, appear reason, weather situation against the dust weather that appeared in recent years in Shijiazhuang district, the analysis found: Dust weather generally reduced in recent years in Shijiazhuang, and mostly concentrated in spring. The geographic distribution of raising dust and sandstorm is dependent on the distribution of dust sources, while the geographic distribution of floating dust is closely related to the upriver effect, wind direction and landform. Upriver effect plays an important role on the formation of dust weather. The weather situation that generates the strong wind and sandstorm are usually the same. The key to the dust weather forecasting is the drought and little rain prophase, and forecast 4-5 strong wind in the future. Upriver effect is the key to the dust weather forecasting. The other key of the sandstorm forecasting is that there is strong convection weather or accompanied by the high altitude rush.
dust weather feature upriver effects forecast.
