TL;DR: Modifications to the Kain‐Fritsch convective parameterization evolved from an effort to produce desired effects in numerical weather prediction while also rendering the scheme more faithful to observations and cloud-resolving modeling studies.
Abstract: Numerous modifications to the Kain‐Fritsch convective parameterization have been implemented over the last decade. These modifications are described, and the motivating factors for the changes are discussed. Most changes were inspired by feedback from users of the scheme (primarily numerical modelers) and interpreters of the model output (mainly operational forecasters). The specific formulation of the modifications evolved from an effort to produce desired effects in numerical weather prediction while also rendering the scheme more faithful to observations and cloud-resolving modeling studies.

TL;DR: In this article, the authors present an analytical model that distributes point measurements of monthly and annual precipitation to regularly spaced grid cells in midlatitude regions, using a combination of climatological and statistical concepts to analyze orographic precipitation.
Abstract: The demand for climatological precipitation fields on a regular grid is growing dramatically as ecological and hydrological models become increasingly linked to geographic information systems that spatially represent and manipulate model output. This paper presents an analytical model that distributes point measurements of monthly and annual precipitation to regularly spaced grid cells in midlatitude regions. PRISM (Precipitation-elevation Regressions on Independent Slopes Model) brings a combination of climatological and statistical concepts to the analysis of orographic precipitation. Specifically, PRISM 1) uses a digital elevation model (DEM) to estimate the “orographic” elevations of precipitation stations; 2) uses the DEM and a windowing technique to group stations onto individual topographic facets; 3) estimates precipitation at a DEM grid cell through a regression of precipitation versus DEM elevation developed from stations on the cell's topographic facet; and 4) when possible, calculates...

TL;DR: In this paper, Lanczos filtering is used to reduce the amplitude of the Gibbs oscillation, which is the principal feature of the Lanczos filter, and a pair of graphs is developed that can be used to determine filter response quality given the number of weights and the value of cutoff frequency.
Abstract: A Fourier method of filtering digital data called Lanczos filtering is described Its principal feature is the use of “sigma factors” which significantly reduce the amplitude of the Gibbs oscillation A pair of graphs is developed that can be used to determine filter response quality given the number of weights and the value of the cutoff frequency, the only two inputs required by the method Examples of response functions in one and two dimensions are given and comparisons are made with response functions from other filters The simplicity of calculating the weights and the adequate response make Lanczos filtering an attractive filtering method

TL;DR: In this article, analytical expressions which specify non-dimensionalized wind speed and potential temperature gradients as functions of stability are integrated with Swinhank's wind and temperature profiles measured at Kerang, Australia.
Abstract: Analytical expressions which specify non-dimensionalized wind speed and potential temperature gradients as functions of stability are integrated. The integrated equations are tested against Swinhank's wind and temperature profiles measured at Kerang, Australia. It is found that a representation suggested independently by Businger and by Dyer gives the best fit to temperature profiles and describes the wind profiles equally as well as a relation suggested by Panofsky et al.

TL;DR: In this paper, the saturation vapor pressure and temperature for moist air were derived for the meteorologically interesting region of −80 to +50°C. The equations are designed to be easily implemented on a calculator or computer and can be used to convert in either direction.
Abstract: Equations are presented which relate saturation vapor pressure to temperature for moist air. The equations are designed to be easily implemented on a calculator or computer and can be used to convert in either direction. They are more accurate than the commonly used Goff-Gratch equations for the meteorologically interesting region of −80 to +50°C. Equations also are given for the enhancement factor.
