The study of relationship between climatic extremes and morbidity is considered one of the key problems of environmental healths. The problem has not lost its topical significance for Mongolian population. Population based, and descriptive study designs were applied in this survey. We have determined average total morbidity of the Mongolian population based on international 10th classification of diseases.1 Average climatic extremes in year has been calculated by the index of Bodmen. Relationship between average yearly climatic extremes of Mongolia and average total morbidity of Mongolian population has been discovered by the geographical method. It has been observed that there are two zones where high climatic extremes in the Mongolian landscape. Statistically significant correlations appeared in the corridors of longitudes: 920-930, 940-1000, 1010-1050, 1060-1070, 1080-1110, 1130-1140, 1160-1170, and in the corridors of latitudes: 420-430, 440-450, 460-470, 480-510 between average yearly climatic extremes of Mongolia and average total morbidity of the Mongolian population.
