Climatology, an old field of scientific investigation in its own right, has many contacts with other fields.Climate influences agricultural, hydrology, human health and disease, forestry, transportation, and manyother fields. Accurate information about the distribution of climate variables in space is the basis forscientifically understanding global or regional changes in processes involving water and its associatedmaterials and energy, which is of great significance for the promotion of meteorological and hydrologicalmonitoring and forecasting to enhance the capability to cope with natural disasters and optimize waterresources management. Surface modeling of climatic change has been a vital scientific issue of commonconcern in many fields, such as meteorology, hydrology, ecology, geology, environment, and so on.
