图11 1961—2022年华北夏季对应EOF3的200 hPa(a)、500 hPa(b)气候平均位势高度(等值线)及高度距平(填色)(单位:dagpm)和200 hPa(a)、850 hPa(c)水平风速异常(箭矢,单位:m·s-1)空间分布 (异常场是对EOF3时间系数PC3回归重构的结果) |
Fig.11 Spatial distributions of climatological mean geopotential height (isolines) and height anomaly (the color shaded) at 200 hPa (a) and 500 hPa (b) (Unit: dagpm) and horizontal wind speed anomalies at 200 hPa (a) and 850 hPa (c) (arrow vectors, Unit: m·s-1) corresponding to EOF3 in summers during 1961-2022 in North China (The anomalous are the result of regression reconstruction upon the time coefficient PC3 of the EOF3) |
