    A radiosonde radiometer (1966)
    Springer
    Pure and applied geophysics 64 (1966), S. 212-219

    Notes: Summary An inexpensive and simple form of radiometer capable of attachment to the American Bureau of Standards type radiosonde is described: it measures the upward flux of longwave radiation when used on night ascents. A slight modification to the telemetry circuit of the standard radiosonde enables the radiation signals to be obtained in addition to the usual pressure, temperature and humidity information.

    The incidence of the sudden infant death syndrome in relation to climate (1982)

    Notes: Abstract Incidences of the sudden infant death syndrome (SIDS) for eight metropolitan communities in U.S.A. are shown to correlate strongly with the mean percentages of cold-wet weather experienced by these places in the seven months centred on January. For white infants aged 4–51 weeks at death, the incidence varies from about one per thousand live births in the more favourable climates to around two per thousand under the less favourable conditions of northwest U.S.A. Incidences are higher for the nonwhite infants but exhibit a similar variation with climate. To be able to extend the study to other countries for which cold-wet weather percentages are not available, a surrogate cold-wet weather index is developed, based on mean cold-season temperature, insolation and number of days with precipitation. Australian and British SIDS incidences related to the surrogate cold-wet weather index exhibit a variation parallel to that for U.S.A. but somewhat higher over the whole range. The incidences used in this study are from the more extensive investigations in which diagnosis was made as a result of thorough postmortem examination.

    The role of coral mucus in reducing the wind drag over coral reefs (1979)
    Springer

    Notes: Abstract The surprisingly small wind stress on the water over a fringing coral reef, which was observed by Hicks et al. (1974), raised the question as to whether this was mainly a shallow water effect or could be the effect of a surface film of organic surfactant. This is considered in relation to other evidence on the shallow water effect and to the fact that coral secretes mucus containing much cetyl palmitate (Benson and Muscatine, 1974). On hydrolysis this yields two powerful surfactants of a type found in natural sea slicks, so the surface film effect is concluded to be the predominant influence. It is conjectured that mucus secretion may have a role in reef ecology by producing quieter water conditions for the more delicate forms of coral typically found some distance shoreward of the windward reef edge.

    Sea-air gas transfer: The wind speed dependence (1981)
    Springer

    Notes: Abstract The rates of transfer of radon from sea to air estimated by Peng et al. (1979) from an extensive series of observations of radon profiles made during the Geosecs oceanographical cruises, are reexamined in relation to wind speed dependence. It is concluded that there is a significant increase with wind speed, but the extent of the increase is uncertain. At 7 m s-1, the transfer velocity is indicated to be some 33%; greater than the BOMEX value of Broecker and Peng (1974) — a reasonably close agreement These rates exceed the theoretical smooth-surface value by a factor of two or three. It is shown that little of this excess can be attributed to the surface dilation effect of capillary waves.

    A note on the effect of wind variability on air-sea gas transfer by the radon method (1984)

    Notes: Abstract The radon deficit method of measuring gas transfer from the sea has so far failed to give reliable information on the dependence of transfer velocity on wind speed owing to the 5.5 day mean lifetime of the radon nuclide. Calculations with a simple model illustrate how the normal variations in wind speed encountered during trials at sea cause even a strong dependence to be largely obscured.

    The streamwise Kolmogoroff constant (1988)
    Springer
    Boundary layer meteorology 42 (1988), S. 9-17

    Notes: Abstract Observations over grassland of the turbulent kinetic energy in a band of frequencies in the inertial subrange of the spectrum of the streamwise wind component are related to the stress indicated by the wind profiles. The object is to determine the effective Kolmogoroff constant, α UB , which accords with the assumption of balance between turbulent energy production and dissipation. The mean from 60 half-hour runs made under stability conditions ranging from neutral to moderate instability is α UB = 0.62. This result is compared with those from other studies; four over grassland and six over the sea or a lake. There is no significant difference between the means of the land and sea values, but the latter are more scattered, partly because of difficulties in securing suitable exposure of the instruments for the stress measurements. The mean value from all ten sets of observations is α UB = 0.59 ± 0.025. So the dissipation method should be capable of giving the drag coefficient of the sea in strong winds with an uncertainty of no more than about 10%.

    Geostrophic drag coefficients (1973)
    Springer
    Boundary layer meteorology 5 (1973), S. 321-340 
    Details

    Notes: Abstract Data on the relationship of the surface wind to the geostrophic wind at Porton Down, Salisbury Plain, are presented for various stability conditions and analysed in the light of the Rossbynumber similarity theory. For near-neutral conditions, the geostrophic drag coefficients for geostrophic wind speeds 5 to 15 m s-1 are close to those found by other workers but at higher speeds the values are low. Comparisons of geostrophic and radar wind speeds for ⋍900-m height, suggest that undetectably small mean cyclonic curvatures of the trajectories of the air are responsible for this departure. A value of the geostrophic drag coefficient for the open sea at wind speeds around 8 m s-1 (neutral conditions) is deduced from recent observations of the drag in relation to the surface wind, combined with the ratios of 900-mb radar wind to surface wind obtained from the North Atlantic weather ship data tabulations of Findlater et al. (1966).
