Abstract : Extensive data and a brief discussion pertaining to two occluded fronts which passed Seattle on March 8 and 10, 1961 are given. The data include: (1) serial ascent radiosonde data, both listed and plotted, (2) radar records from the continuously recording 1.87 cm vertically-directed radar, (3) time section, (4) synoptic surface and constant pressure analyses, (5) hourly surface charts, (6) barograph and temperature traces, and (7) pilot reports. The first storm is notable for the lack of warm frontal structure and the part played by evaporation in the modification and propagation of the frontal zone. The second storm exhibited an occluded frontal structure up to 350 mb. Such a situation is unusual, but the data clearly indicate the passage of a sharp boundary between warm and cold advection regions at Seattle while the warm sector air mass remained south of Oregon.
