Weather and Climate in Tibet (p. 64) 
E.R. Reiter’s Jet Streams (Garden 
City: Doubleday and Co., Inc., 1967) is 
the first popular survey of this phenom- 
enon. Beginning with a chapter on the 
discovery of jet streams. Reiter then ex- 
plores how they are formed; how they 
move, are measured, and analyzed; and 
what effect they can have on weather 
and climate. Reiter also gives an excel- 
lent survey of the basic methods of me- 
teorological investigation. “Rapid 
Rivers of Air,” by E.R. Reiter ( Natural 
History, March 1975, pp. 46-51), re- 
views the effects of jet streams on 
weather, climate, agriculture, and avi- 
ation (see that issue’s “Additional 
Reading,” p. 84, for four more refer- 
ences). H.H. Lamb’s two- volume Cli- 
mate: Present, Past and Future 
(London: Methuen and Co., Ltd., 
1972) is an essential, authoritative ref- 
erence work on climate fundamentals 
and history. This exhaustive study also 
discusses how to approach such prob- 
lems as seasonal forecasting and advis- 
ing on future climatic trends. Part one 
has 613 pages; part two has 835. The 
January 1981 issue of the Bulletin of the 
American Meteorological Society con- 
tains six articles by scientists who par- 
ticipated in an excursion by jeep across 
Tibet, organized by Academia Sinica 
and the Chinese government (pp. 
4—36). The articles deal with local and 
regional meteorological and climato- 
logical problems in Tibet. S. Han’s Lha- 
sa, the Open City (London: Jonathan 
Cape, Ltd., 1977) is an anecdotal, con- 
versational account of the changes, 
brought about by the diminished role of 
the religious elite and the increased role 
of the former serf class, that occurred in 
Tibet from 1950 to the present day. 
Han describes the effects of Chinese 
Communist influence, which she con- 
siders to be especially important and 
presents in a positive light. “Tibet-in- 
Exile: Triumph of a People,” by J. Ave- 
don, with photographs by E. Haas and 
D. Mehta (GEO, May 1981, pp. 
84-110), is about the 85,000 Tibetans 
who, after a violent, unsuccessful upris- 
ing in 1959 against Chinese domination, 
fled to India with their leader, the Dalai 
Lama, and created a nation-in-exile.

Erratum; The caption on page 46 of our 
August issue incorrectly identifies the 
avocet (top photo) as engaging in a dis- 
traction display, when it is, in fact, per- 
forming a two-wing stretch display. 
This behavior often precedes flight 
from a disturbance.
