We held a workshop of Klimaatlas on 23th and 24th November 2003 in Sendai. This workshop was held for examinations of making process of the climate analysis map and the recommendation map based on climate analysis data at summer. We took up 3 areas, near the seashore, residential sections on hill and central district of Sendai city. Through three sub-committee meetings, the maps were made based on various data, for example climate analysis data (include the results of numerical analysis), land use maps, and city planning data and so on. After that, we discussed about what is urban environmental problems in Sendai. As the result, it is cleared that we must consider characteristics of regional climate when we design urban planning.
