TREND ANALYSIS: TEMPERATURE, HUMIDITY AND PRECIPITATION
"Climate Change in the Yellowstone National Park: Is the
Drought-Related Risk of Wildfires Increasing?" R.C. Balling Jr. (Off.
Climatol., Arizona State Univ., Tempe AZ 85287), G.A. Meyer, S.G. Wells, Clim.
Change, 22(1), 35-45, Sep. 1992.
Comparison of annual wildfire data to variations in historical climate
conditions shows that summer temperatures in the park are increasing,
January-June precipitation is decreasing, and variations in burn area are
related to climatic variations. GCM predictions of increasing aridity in the
park area under doubled CO2 are in general agreement with trends in the
historical climate records.
"Observational Signs of Greenhouse-Gas-Induced Climate Change, with
Special Reference to Northern Latitudes," C.D. Schönwiese (Goethe
Univ., Inst. Meteor., Feldbergstr. 47, D-6000 Frankfurt 1, Ger.), J. Atmos.
Terr. Phys., 54(9), 1101-1106, Sep. 1992.
Northern Hemispheric surface air temperature and precipitation data over the
last 100-130 years were statistically analyzed and correlated with volcanic,
solar, ENSO, North Atlantic Oscillation and greenhouse gas forcings, to separate
any anthropogenic climate signals from natural variability. Temperature
assessments were also compared to results of deterministic climate model
"Climatic Variability of Temperature and Humidity over the Tropical
Western Pacific," D.S. Gutzler (Aeron. Lab., NOAA, 325 Broadway, Boulder CO
80303), Geophys. Res. Lett., 19(15), 1595-1598, Aug. 3, 1992.
The vertical structures of recent decade-scale trends were studied using
radiosonde data from four stations. Both temperature and specific humidity have
increased throughout the troposphere since the mid-1970s. Specific humidity in
the tropics is shown to be a sensitive indicator of long-term climate change.
Reproduction of the vertical structures observed in this study would be a good
test of model projections of climate change.
"Growing Season Trends in the Alaskan Climate Record," B.S.
Sharratt (ARS, USDA, 309 O'Neill Bldg., Univ. Alaska, Fairbanks AK 99775), Arctic,
45(2), 124-127, June 1992.
Data from half of the eight stations studied showed no change in growing
season over the past 65 years; the season lengthened at the other four stations.
The season shortened at three stations during the period 1940-1970,
corresponding to declining Northern Hemisphere temperatures.
"Assessing the Value of Historical Temperature Measurements," A.
McConnell (Sci. Museum, London, England), Endeavour, 16(2),
80-84, June 1992. Reviews the accuracy of past records with respect to
instruments, their exposure, and the observers.
"Long-Term Surface Temperature Variations in South Africa," A.
Muhlenbruchtegen (Univ. Witwatersrand, Climatol. Res., Witwatersrand 2050, S.
Africa), S. African J. Sci., 88(4), 197-205, Apr. 1992.
Monthly data were examined for temporal and spatial trends in mean, minimum
and maximum temperatures. Monthly means show little trend over the past 50
years, while both increasing and decreasing trends were noted in minima and
Comment on spectrum analysis of oscillations in the IPCC temperature
record, Nature, 356(6372), 751, Apr. 30, 1992.
"The Impact of Snow Cover on Diurnal Temperature Range," R.S.
Cerveny (Off. Climatol., Arizona State Univ., Tempe AZ 85287), R.C. Balling Jr.,
Geophys. Res. Lett., 19(8), 797-800, Apr. 24, 1992.
Demonstrates an inverse correlation between the area of North American snow
cover and the U.S. diurnal temperature range. Because global warming is expected
to reduce the areal extent of snow cover, it should act to increase the diurnal
temperature range, in contrast to the decrease recently observed in many areas
of the world. The link between temperature range and greenhouse gases may be
complicated by feedback processes.
