The correlations between moon phases and precipitation maximums were investigated for selected stations in British Columbia in order to determine if they existed for: (a) individual stations; (b) grouped stations; (c) annual occurrences; (d) seasonal occurrences; and (e) geographic areas. The analysis consisted of a graphical presentation and a statistical test for randomness. Graphs of annual and seasonal moving totals for grouped and Individual stations were prepared. They were analyzed for peaks in the configuration of the graphs and for annual and seasonal components through the use of the X2p test. It is apparent from this study that there is a relationship between moon phases and precipitation maximums for grouped stations and individual stations in British Columbia. The evidence for the annual components of "lunar" precipitation for the individual stations shows, statistically, that the distributions are non-random and, graphically, that peaks are visible. Moreover, a shift of the peaks with latitude is discernible for the stations of British Columbia and it is suggested that this shift exists on a global scale. The evidence for the seasonal components of "lunar" precipitation for the individual stations is not as conclusive, either statistically or graphically. The seasonal graphs show peaks but the test for randomness yields inconsistent results. / Arts, Faculty of / Geography, Department of / Graduate

Occult deposition is the direct uptake of cloudwater by vegetation that comes into physical contact with wind-driven cloud droplets. This can be a significant pathway for hydrological and chemical fluxes from the atmosphere to some forests. Methods for estimating cloudwater fluxes to forests are reviewed. Previous studies have neglected the fact that cloudwater is not a conservative atmospheric quantity. This invalidates traditional micrometeorological approaches for estimation of cloudwater fluxes to forests. A theory is developed to predict the change in the cloudwater flux with height due to condensation in the updrafts of orographic cloud, allowing estimation of surface uptake via eddy correlation measurements while accounting for condensation. The performances of three microphysical instruments are examined. From collocated measurements, errors in cloud liquid water content are determined for a Particulate Volume Monitor (PVM) and a Forward Scattering Spectrometer Probe (FSSP) to be less than 0.01 g m⁻³ and 0.035 g m⁻³ respectively. Similarly, the error bounds for surface-normal cloud liquid water fluxes are found to be 2 mg m⁻² s⁻¹ for the PVM and 3.5 mg m⁻² s⁻¹ for the FSSP. Smaller errors are found to be associated with the uncertainty in the direction of the flux relevant to surface uptake. The FSSP is seen to have larger errors when droplet concentrations exceed 600 cm⁻³. A vertical divergence is detected in the cloudwater flux; the downward flux decreases with increasing distance from the surface, usually changing sign by 15 m above ground. Five candidate processes are identified as possible explanations for this measured flux divergence. A scale analysis shows that the liquid water source (condensation due to pseudoadiabatic ascent) is largely responsible for the change in flux with height. Accounting for the change in flux with height results in a near doubling of the estimated surface flux relative to the flux measured at a height of 10 m in the surface layer for this silver fir forest. This factor applies to chemical as well as liquid water fluxes. This source of liquid water also is seen to be important in developing a simple model for cloudwater deposition. / Graduation date: 1997
