K Mitra Biología rainfall Barnes scheme mesoscale analysis monsoon depression An objective analysis of daily rainfall over Maharashtra (India) by distance weighting function on a mesoscalegrid is described. The Barnes scheme is applied to interpolate irregularly distributed daily rainfall data on toa regular grid. The spatial resolution of the interpolated arrays is 0.25 degrees of latitude by 0.25 degrees of longitude. Some objectively determined constraints are employed in this study: (i) weights are determined asa function of data spacing, (ii) in order to achieve convergence of the analyzed values, two passes throughthe data are considered, (iii) grid spacing is objectively determined from the data spacing. The case of atypical westward moving monsoon depression during the 1994 monsoon season is chosen for this study.Objective analyses of six days (16 to 21 August 1994) have been carried out using variable length scale twopass (V2P) and fixed length scale two pass (F2P) Barnes scheme. A length scale of 80 km for the outer pass and40 km for the inner pass are considered. Analyses show moderate improvement of V2P scheme over F2Pscheme. The bias of the analysis based on V2P is 2% lower than that of analysis based on F2P. 2006 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56519203 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.2 Vol.19 |
