transient motions are largely filtered out, leaving behind the predominantly stationary part. The absolute values of the ratios of the amplitudes of the finite-difference and exact solutions have been chosen as the measure of the error introduced by the finite-differencing. Results obtained suggest that with reasonable resolution the horizontal space arrangement of dependent variables may affect the finite-difference solutions on the synoptic scales.

Fifteen tropical cyclones occurred during 1985-86 compared with the ten-year average of about thirteen. Five cyclones reached the severe category. Widespread major damage and three fatalities were attributed to Winifred, one of only two cyclones to cross the coast (compared with the 21-year average of 4.8). A maximum gust of 176 km h -I was recorded during her passage. Two cyclones commenced during May, only the second time two May cyclones have affected the Australian region since 1964. Reg.

A band-pass filter is used to obtain an estimate of the seasonal CO2 cycle at Mauna Loa from monthly mean concentration data. The signal shows interannual variations in the amplitude with a preponderance of larger amplitudes in recent years. Abnormally small amplitude peaks in the (northern) spring are almost always followed by small-amplitude troughs in the following fall but there is no similar correlation between the amplitudes of peaks in fall and the following spring. This suggests that the amplitude variations reflect changes in individual northern growth seasons. Div. of Atmos. Res., CSIRO, Private Bag 1, Mordiailoc, Vie., Australia. 87:6161 Lindzen, R.S., 1987.

(a translation of Meteorologiya Gidrol.), 10:5056. Based on a new integral approach the authors analyze the calculated mean latitudinal phase differences of the annual course and heat fluxes for the World Ocean. Differences between oceans are discussed in terms of their role in global heat exchange. Values of the meridional heat fluxes reveal an asymmetry of fluxes in the Pacific and the Atlantic.

Dry conditions plague parts of the Northern Hemisphere. Mon. Weath. Rev., 115(3):705-720. For the second consecutive summer, significant areas of the Northern Hemisphere experienced drier than normal conditions. One of the most severely affected was the southeastern United States. In addition, drier than normal conditions were again prevalent in the monsoon regions of India, southeast Asia, and the African Sahel and also affected southwestern France and northern Spain during June and July. In contrast, abundant to excessive rainfall fell throughout parts of the Southern Hemisphere. Areas of central Australia received 400-500% of their average wintertime precipitation. During December-February and March-May, tropical Pacific indicators of the warm phase of the

The multilayer energy balance model of Peng et al. (1982) has been further developed to study long-term transient climate response to CO~ increase. For a hypothetical doubling of atmospheric CO_,, the model approximates an equilibrium response of global mean surface temperature in 9-35 yr, depending upon the probable range of vertical heat diffusivity in the ocean. In response to a generally accepted CO 2 trend, the model's transient response in annually and globally averaged surface temperature is 60--75% of the equilibrium response. When the CO x level doubles in about a century, global mean surface temperature increases by 1.5-2.0C °. Local warming at certain times of the year, however, may be 2-3 times greater. The pattern of seasonal and latitudinal distribution of transient response remarkably resembles that of the equilibrium response. The model also shows that CO2 increases prior to 1975 have minimal effects on model responses after the year 2000. Univ. Space Res.
