HISTORIC CLIMATES

Item #d99apr23

“The Early 19th Century Climate of the Bahamas and a Comparison with 20th Century Averages,” Michael Chenoweth,Climatic Change 40, 577-603 (1998).

Bahamian temperature records from 1811 to 1845 were compared with observations from 1961 to 1990 and revealed that, in the latter period, annual average temperatures were 0.4° C warmer, rainfall was more frequent, and gale- force winds were 85% more frequent. In the earlier period, winds were more northerly, indicating that high pressure over the southeast United States was more common then.

“On the Use of the Jesuit Order Private Correspondence Records in Climate Reconstructions: A Case Study from Castille (Spain) for 1634–1648 A.D.,” F. S. Rodrigo, M. J. Esteban-Parra, and Y. Castro-Diez,Climatic Change 40, 625-645 (1998).

The private letters of members of the Jesuits from 1634 to 1648 revealed climate information for that period in Castille, showing that intense rainfall and cold air waves swept the Iberian Peninsula during the Little Ice Age.

Item #d99apr25

“Northern North American Tree-Ring Evidence for Regional Temperature Changes after Major Volcanic Events,” R. D. Darrigo and G. C. Jacoby,Climatic Change 41, 1-15 (1999).

Tree-ring data at 13 sites along the northern treeline in Canada and the United States showed varied responses to known volcanic eruptions in 1640, 1783, 1815, and 1835. The regional variation is attributed to the distribution of volcanism-induced cooling by atmospheric circulation patterns.
