    Description: Continuous estimates of the oceanic meridional heat transport in the Atlantic are derived from the Rapid Climate Change–Meridional Overturning Circulation (MOC) and Heatflux Array (RAPID–MOCHA) observing system deployed along 26.5°N, for the period from April 2004 to October 2007. The basinwide meridional heat transport (MHT) is derived by combining temperature transports (relative to a common reference) from 1) the Gulf Stream in the Straits of Florida; 2) the western boundary region offshore of Abaco, Bahamas; 3) the Ekman layer [derived from Quick Scatterometer (QuikSCAT) wind stresses]; and 4) the interior ocean monitored by “endpoint” dynamic height moorings. The interior eddy heat transport arising from spatial covariance of the velocity and temperature fields is estimated independently from repeat hydrographic and expendable bathythermograph (XBT) sections and can also be approximated by the array. The results for the 3.5 yr of data thus far available show a mean MHT of 1.33 ± 0.40 PW for 10-day-averaged estimates, on which time scale a basinwide mass balance can be reasonably assumed. The associated MOC strength and variability is 18.5 ± 4.9 Sv (1 Sv ≡ 106 m3 s−1). The continuous heat transport estimates range from a minimum of 0.2 to a maximum of 2.5 PW, with approximately half of the variance caused by Ekman transport changes and half caused by changes in the geostrophic circulation. The data suggest a seasonal cycle of the MHT with a maximum in summer (July–September) and minimum in late winter (March–April), with an annual range of 0.6 PW. A breakdown of the MHT into “overturning” and “gyre” components shows that the overturning component carries 88% of the total heat transport. The overall uncertainty of the annual mean MHT for the 3.5-yr record is 0.14 PW or about 10% of the mean value.

    Notes: Fluid-mechanical aspects of a unique drop-tube apparatus to promote spherically symmetric evaporation and combustion of freely falling droplets are discussed. Design of the apparatus is based upon the principle that gravitationally induced pressure gradients in gases may be significantly reduced by accelerating the gases with properly contoured tubes. Droplets traveling with the gases will experience greatly reduced buoyancy and forced convection environments, promoting spherical symmetry. For specification of tube contours, the Navier–Stokes and continuity equations are recast into a vorticity-stream function formulation and solved numerically with pseudospectral methods. Axisymmetric tube contours which produce desired velocity and pressure fields are found, and implications for designs and limits of experimental apparatus are discussed.

    Notes: Simplified analyses using a linear stability approach are developed to predict influences of thermal and solutal Marangoni effects on hydrodynamic stability of bi-component droplets evaporating in a spherically-symmetrical manner in hot environments. It is predicted that with zeotropic mixtures and for ∂σ/∂T〈0 and ∂σ/∂y〈0 (where σ is surface tension, T temperature, and y the surface mass fraction of the more volatile droplet component), the thermal and solutal Marangoni effects oppose each other in that the thermal effect is stabilizing and the concentration effect is destabilizing. The model is applied to alkane/alkane and alcohol/water mixture droplets. The alkane mixture droplets were predicted to be hydrodynamically stable. For alcohol/water mixtures, the results suggest that critical radii for marginal stability exist; when a droplet is initially pure methanol which subsequently absorbs water from the ambient, the critical radius is predicted to depend upon the relative humidity of the environment. © 1996 American Institute of Physics.

    Notes: Summary. The consumption of water by weeds was determined on the basis of the loss in yield of timber suffered by 28–32–year-old plantations of red pine (Pinus resinosa Ait.). Soil and biomass analyses included several pairs of closely located stands established simultaneously on either cultivated or weed-supporting soils. The water supply of 1050 metric tons/ac, available during the growing season, was estimated as the algebraic sum of precipitation, winter storage, condensed vapour, evaporation of intercepted rainfall and gravitational discharge. The biomass of plantations on soils of satisfactory nutrient content and aeration consumed about 500 kg water for production of 1 kg dry matter. The diversion of available water by weed cover on soils of high potential site indices approached 100 kg per kg oven-dry tissues. Blueberries, sweet fern and other heath plants, with initial weight of about 10 metric tons/ac, caused more than 50% loss in the expected volume of merchantable timber. The established relations facilitate an estimate of the productive potential of weed-supporting soils and the choice of an appropriate tree spacing of forest plantations. Les mauvaises herbes, facteur inhibant de la croissance des essences forestières 〈section xml:id="abs1-1"〉〈title type="main"〉Résumé.La consommation d'eau par les mauvaises herbes a étéévaluée en rapport avec la perte de rendement en bois éprouvée par des plantations de pins rouges (Pinus resinosa Ait.) âgés de 28 à 32 ans. Des analyses du sol et de l'ensemble de la végétation ont été effectuées simultanément par paires dans des stations voisines sur des aires maintenues propres par des facons culturales ou infestées de mauvaises herbes. L'apport d'eau, de 2625 tonnes a l'hectare durant la pdriode de croissance, fut considéré comme la somme alg6– brique des precipitations, du stockage hivernal, de la condensation de la vapeur, de l'éva-poration de la pluie interceptée et de l'e'coulement par gravité. L'ensemble de la masse végétale des plantations, sur des sols d'un niveau de fertilité satisfaisant et convenablement aérés, consomme environ 500 kg d'eau pour la production de 1 kg de matiére séche. Le détournement d'eau disponible par la couverture des mauvaises herbes sur des sols à haut potentiel de fertilité approcha de 100 kg par kg de tissu dessé chéà l'étuve. Les myrtilles, les Myrica ('sweet fern’) et autres plantes de landes, avec un poids initial d'environ 25 tonnes a l'hectare provoquerent une perte de plus de 50% du volume attendu de bois commercialisable. Les relations établies facilitent l'estimation du potentiel de production des sols infestéd de mauvaises herbes et le choix d'un espacement approprié entre les arbres dans les plantations forestières.
