Continuous Cropping and Moist Deep Convection on the Canadian Prairies
Summerfallow is cropland that is purposely kept out of production during a growing season to conserve soil moisture. On the Canadian Prairies, a trend to continuous cropping with a reduction in summerfallow began after the summerfallow area peaked in 1976. This study examined the impact of this land-use change on convective available potential energy (CAPE), a necessary but not sufficient condi...
متن کاملAtmospheric Moist Convection
■ Abstract Various forms of atmospheric moist convection are reviewed through a consideration of three prevalent regimes: stratocumulus; trade-wind; and deep, precipitating, maritime convection. These regimes are chosen because they are structural components of the general circulation of the atmosphere and because they highlight distinguishing features of this polymorphous phenomenon. In partic...
متن کاملAnnual Climatology of the Diurnal Cycle on the Canadian Prairies
We show the annual climatology of the diurnal cycle, stratified by opaque cloud, using the full hourly resolution of the Canadian Prairie data. The opaque cloud field itself has distinct cold and warm season diurnal climatologies; with a near-sunrise peak of cloud in the cold season and an early afternoon peak in the warm season. There are two primary climate states on the Canadian Prairies, se...
متن کاملOn the Transient Behavior of Asai’s Model of Moist Convection
I The transient behavior of the simple model of moist convection devised by Asai is studied. It is shown that the initial behavior of convective disturbances depends strongly upon the geometry of the disturbance, its initial buoyancy, and dissipative mechanisms. Final approach to a steady convective cell is dependent upon the relative importance of entrainment of heat and momentum. These conclu...

SETTING The prairie provinces of Canada. OBJECTIVE To characterize tuberculosis (TB) transmission among the Indigenous and non-Indigenous Canadian-born peoples of the prairie provinces of Canada. DESIGN A prospective epidemiologic study of consecutively diagnosed adult (age ≥ 14 years) Canadian-born culture-positive pulmonary TB cases on the prairies, hereafter termed "potential transmitter...
