Download or read book Some Performance Comparisons Between NMC s Spectral Model and the Seven layer Primitive Equation Model written by Donald G. Marks and published by . This book was released on 1983 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of NMC's new global spectral model is compared to the performance of the older, seven-layer, grid-point primitive equation model which it replaced. Since it has been in operation since August 1980, mean error statistics may be used to determine this performance. In general, the spectral model shows a distinct improvement in overall forecast skill. The spectral model especially shows an improvement in wave amplitudes and generally stronger flow. Much of this improvement occurs in the longer waves and leads to greatly improved medium range forecasts.

This book was released on 1989 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using forecast relative humidity (RH) from a global model, several pre-existing diagnostic RH-to-cloud schemes were tested to forecast global fractional cloud cover in a postprocessor format. Since none of the schemes tested provided a superior cloud forecast when compared to Air Force Global Weather Central's (AFGWC) operational 5LAYER cloud forecasts, a new RH-to-cloud scheme was developed by relating cumulative frequencies of forecast RH to cumulative frequencies of analyzed cloud cover from the AFGWC RTNEPH cloud analysis. This scheme creates a series of forecast time-dependent RH-to-cloud curves that can be temporally updated to account for changes in season, cloud analysis, or forecast model, The global model used was a spectral-type developed by the Geophysics Laboratory (GL) using parameterized diabatic physics presently incorporated in the operational GSM (global spectral model) at AFGWC.

This book was released on 1990 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The procedures and results of a study undertaken to evaluate and assess the impacts of three new parameterization schemes for the GL global spectral model as a 3-4 day range forecast model are described. The tree parameterization schemes are one each for the boundary-layer physics, moist convection and heating due to solar and terrestrial radiations. These schemes are incorporated either singly or jointly into a rhomboidal-30, 12-layer global spectral model for four-day simulations using FGGE III- a data as input. Evaluation and assessment are made on the basis of two kinds of global statistics: mean and root-mean-square errors, and on their magnitudes and distributions. The statistics are generated for both the primary, that is, prognostic, variables, and supplementary variables such as zonal-mean and zonal-eddies energy densities. The new moist convection scheme has been found to increase convective activity significantly and maintain it throughout the four-day period. It also warms and dries the middle troposphere, but produces rainfall far in excess of the climatology. The radiation parameterization has been found to cool the atmosphere and reduce its specific humidity. It counterbalances enhanced heating and moistening brought about by the new boundary-layer and moist convection schemes and eliminates the systematic warming of the old model.

Available in PDF, EPUB and Kindle. Book excerpt: It is a well known fact that with the existing level of available technology, India can easily double its agricultural production and productivity. However, what is preventing us from achieving the above production level is the lack of an efficient administrative organisation which can take the benefits of technological advances to the door steps of farmers. It is clear that the most important issue to be tackled with regard to agricultural development in India in the coming years is not the fabrication of new technologies but development of efficient organisations which will transfer the available technologies into production accomplishments. Thus there is a need for scientific study of organisations dealing with agricultural development. There are very few investigations on functioning of agricultural administration .The present study has been undertaken to analyse the structure, processes and functioning of agricultural administration of agriculturally developed and less developed states. Does the agricultural administration of developed state significantly differ from that of less developed state significantly differ from that of less developed state? If yes, in what dimensions? The present study provides answer to this question. The book, divided into eleven chapters, gives a comparative account of different organisational aspects of department of agriculture in a developed and a less developed states. The items discussed include organisational context, structure, processes, personnel policies, and effectiveness.
