The linear regression pattern of the (a) 200 hPa wind (vectors, units: m·s−1), (b) The linear regression pattern of 500 hPa geopotential height (shadings, units: gpm), 500 hPa wind (vectors, units: m·s−1), and climatic JA 500 hPa geopotential height (contours, units: gpm) (c) The linear regression pattern of water flux (vectors, units: kg·m−1·s−1) on the PC1 during 1979–2007. Dark (light) stippling indicates values significantly exceeding the 99% (90%) confidence level using Student’s t test in (b) and (c); winds with values under the 90% confidence level are omitted in (a)–(c).
