An Investigation of Small Scale Humidity Fluctuations in the Marine Boundary Layer.
Abstract
Humidity spectra were measured with the Lyman-alpha humidiometer, together with mean profiles of virtual potential temperature, wind, and humidity in the open ocean environment. Empirically derived expressions describing the temperature structure parameter were extended by similarity arguments to the humidity-structure parameter, (C sub q) squared, and (C sub q) squared was related to the stability parameter Ri. Using the above measured parameters, vertical humidity flux was computed in two different manners, and a comparison was made. In general, there was little correlation between the spectrally analyzed (C sub q) squared values and Ri. Results for (C sub q) squared can essentially be regarded as a function of z and humidity gradient. Non-dimensional (C sub q) squared results were generally an order of magnitude smaller than expected. No correlation between the two methods of calculation of humidity flux was found.
