FROM VOLUME 3, NUMBER 10, OCTOBER 1990
"Possible Factors Controlling Global Marine Temperature Variations
Over the Past Century," Z. Wu (Dept. Earth, Atmos. Plan. Sci., 54-1824,
Mass. Inst. Technol., Cambridge MA 02139), R.E. Newell, J. Hsiung, J.
Geophys. Res., 95(D8), 11,799-11,810, July 20, 1990.
Applies statistical techniques to data from the Global Ocean Surface
Temperature Atlas (1856-1988) to estimate physical factors which may have
produced observed fluctuations in the temperature record. With this approach,
the apparent twentieth century temperature increases can be viewed as partly due
to a recovery from cooling at the turn of the century, probably associated with
"The Correlation of Tropospheric and Stratospheric Temperatures and
Its Effect on the Detection of Climate Changes," Q. Liu (Inst. Meteorol.
Phys. Oceanog., Utrecht Univ., Neth.), C.J.E. Schuurmans, Geophys. Res.
Lett., 17(8), 1085-1088, July 1990.
Using 42 years of seasonal mean temperature anomalies in De Bilt, the
Netherlands, shows that one way of detecting climate change is to search for the
signal of an increase of lower stratospheric cooling with increasing altitude.
This method may be able to separate the climatic change due to the external
forces from the atmospheric internal fluctuations.
"Variation in Global Tropospheric Temperature After Adjustment for
the El Niño Influence, 1958-1989," J.K. Angell (NOAA-ARL, 1325 East
West Highway, Silver Spring MD 20910), ibid., 1093-1096.
Data from a 63-station radiosonde network were subjected to regression
adjustment to remove the influence of the El Niño Southern Oscillation.
The increase in decadal-mean temperature between the 1960s and the 1980s is
reduced from 0.33° C to 0.24° C, the annual temperature is a maximum in
1989 rather than in 1988, and there is more evidence that volcanic eruptions in
1963 and 1982 decreased global tropospheric temperatures by about 0.2-0.3° C
for about 3 years.
"A Statistical Trend Analysis of Revised Dobson Total Ozone Data Over
the Northern Hemisphere," R. Bojkov (World Meteor. Org., C.P. No. 5,
CH-1211 Geneva 20, Switz.), L. Bishop et al., J. Geophys. Res., 95(D7),
9785-9807, June 20, 1990.
Reports a detailed analysis focusing on the seasonal, regional and
latitudinal patterns of trends using data from 29 Northern Hemisphere stations
through 1986. Trend results based on published data are on average less negative
than trends from revised Dobson data for European stations, by about 1.0% per
decade across all seasons, with only small average differences for stations in
North America and Japan.
"Climatology Comparison and Long-Term Variations of Sea Surface
Temperature Over the Tropical Atlantic Ocean," J. Servain (Centre ORSTOM,
IFREMER, BP 70, 29280 Plouzané, France), M. Séva, P. Rual, ibid.,
95(C6), 9421-9431, June 15, 1990.
Compares two sea surface temperature (SST) climatologies produced from
merchant ships taken over two periods, 1911 to 1972 and 1964 to 1984. Through a
simple technique to eliminate spurious bias, the analysis allows isolation of
the long-term trend of SST anomalies. Comments on the global long-term trend of
SST in the tropical Atlantic for the past 70 years.
"Confusing Signals in the Climatic Record," R.C. Balling Jr.
(Dept. Geog., Arizona State Univ., Tempe AZ 85287), S.B. Idso, Atmos.
Environ., 24A(7), 1975-1977, 1990.
Uses five data sets to investigate the linear trend in screen-level air
temperature in Arizona for the past 50 years. Disparate results suggest that
even assessing recent historic temperature trends can be difficult.
