| Summary: | In the “Weather Note”, Monthly Weather Review, maximum fall in 3 hours was 26 mb. The maximum January 1960 an unusual pressure rise at Yakutat is pressure rise in 1 hour was from 941.5 mb. at 1740 GMT described [I]. As the note asked for information about to 960.5 mb. at 1840 GMT, or 19 mb. The maximum similar or larger pressure rises, I want to give a brief pressure rise in 3 hours was 33 mb. description of an unusual cyclone with rapid pressure The barograph trace made at Hblar, Southeast Iceland, variations that struck the east coast of Iceland on January was very similar to that ’ at Dalatangi with minimum 25, 1949. This cyclone had a central pressure of about pressure of 947 mb. and maximurn pressure rise of 18 mb. 940.mb., its radius was approximately 200 km., and it in 1 hour. moved with a velocity of about 70 km./hr., N. 15 ’ E. Pressure rises of similar magnitude as that described The most rapid pressure variations occurred at Dah- in [I] have been observed several times at Icelandic tangi, where the following pressure observations were weat’her stations. Three examples observed in Reykjavik made: during the last 12 years are: Sea level pressure |
