Mean atmospheric circulation from 1 May to 14 June for years in which furcilia fractions are greater (A, B) or lesser (C, D) than JAD fractions. A) and C) display mean wind vectors (at every 2nd ith grid point), wind directional constancy (color shading) and statistically-significant correlations between JAD fraction and U-component winds (blue contours) and V-component winds (black contours) with correlation contours at r = 0.60 (p < 0.05) and 0.74 (p < 0.01). B) and D) display mean sea level pressure (hPa) patterns. High and low pressure cells are annotated with H and L, respectively. Maps generated using IDL (Interactive Data Language)/v8.6.
