Much drier air with significantly lower TPW values (30-35 mm or 1.2-1.4 inches, cyan to darker blue color enhancement)<\/em> followed in the wake of the tropical wave passage; this dry air was likely the leading edge of a westward pulse of the Saharan Air Layer<\/strong><\/a> or SAL (real-time SAL images<\/strong><\/a>).<\/p>\n
