Short process annotations identify positive evaporation, the conceptual thermodynamic-dynamic interaction near SAM, and the 850 hPa horizontal wind vector. Site-name text and leader lines are omitted. Site circles retain their exact projected coordinates. SSK168 and NGHP-17 use gold and ivory rings around the nearby pink U1448 circle. Site colors and symbol sizes are categorical and do not encode a measured quantity.",
