Mean atmospheric circulation from 28 September to 24 December for years preceding years in which furcilia fractions are greater (A, B) or lesser (C, D) than JAD fractions. Year annotations indicate krill survey years. A) and C) display mean wind vectors (at every 2nd i th grid point), wind direction...

Description
Summary:Mean atmospheric circulation from 28 September to 24 December for years preceding years in which furcilia fractions are greater (A, B) or lesser (C, D) than JAD fractions. Year annotations indicate krill survey years. A) and C) display mean wind vectors (at every 2nd i th 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.
