| Summary: | oriented east-west, as were temperature anomalies (fig. lob), in the pattern characteristic of the month. This was the fourth consecutive week with below normal temperatures over the central and southern Great Plains, where several new low temperature records were established for March. Additional precipitation this week (fig. 1Oc) contributed to the record-breaking California totals mentioned earlier, as well as to other record accumulations at Albuquerque, N. Mex. and Atlantic City, N. J. From 1 to 2 inches fell over most of a large area southward from a line between southern Virginia and southern Indiana, as the final Gulf storm of the month moved up the east coast. Precipitation remained light along the northern border and over the northern Plains States for the fourth consecutive week. This is an indication of the stability and extent of the great anticyclone over eastern Canada. In summary, the largest single feature of the circulation this month was the blocking High over Hudson Bay. High pressure persisted in this area during each week of the month, and the associated monthly mean DN at 700 mb. was the largest ever observed over North America during March. This Hudson Bay High contributed strongly to low 700-mb. temperate westerly index over the Western Hemisphere and had an even greater influence on United States weather. |
