The characteristic topography near regions such as Chulucanas (roughly in the center, cf., Figures 3, 11, 12 and 13), where such storms were observed to occur on a frequent basis, is ideal for the aforementioned interaction between the rainbands and the Andean foothills. The origin of the east-west rainbands near the north Peruvian coast is less clear but may be caused by low altitude wind surges, which are driven northward along the coast of Peru by a large and quasi-permanent high in the southeastern Pacific.
Investigation of the applicability of other methods of gridding scattered data will be considered for these and similar, but larger sets of meteorological data , , , , , ,  and .
