As of 25 November 2014, much of the state of California was experiencing extreme to exceptional drought<\/strong><\/a> conditions.\u00a0 However, the development of a large occluded mid-latitude cyclone over the far eastern Pacific Ocean during the 01 December – 02 December time period began to draw high values (up to 60 mm or 2.4 inches, darker red color enhancement)<\/em> of total precipitable water (TPW) northward from the Inter-Tropical Convergence Zone (ITCZ), as seen on AWIPS images of the MIMIC TPW product (above)<\/strong><\/em>. While the rainfall was beneficial in terms of drought mitigation, amounts of up to 12 inches<\/strong><\/a> did cause flooding and mudslide problems in some locations.<\/p>\n

An animation of hourly MIMIC TPW images from 30 November – 02 December (below; click image to play animation)<\/strong><\/em> showed the northward surge of moisture toward the California coast, and also hinted at a complex inner structure associated with the occluded low.<\/p>\n

On 02 December, comparisons of AWIPS II images of 1-km resolution MODIS 6.7 \u00b5m and 4-km resolution GOES-15 6.5 \u00b5m water vapor channel data around 11 UTC (above)<\/strong><\/em> and around 22 UTC (below)<\/strong><\/em> demonstrated the importance of improved spatial resolution for more clearly identifying some of the smaller-scale structure features within the core of the occluded low.<\/p>\n
