The main focus to make an understanding on a climate system is that it comprises with many compartments such as cryosphere, biosphere, atmosphere, land and ocean and all these compartments are interacted on each other and stimulates and drives the system by solar energy. The climate change condition express itself by increased air temperature and its impact on soil (agriculture and forest), hydrology and human beings. The main focus is the soil dynamic system and the basic knowledge of soil and water dynamic in soil and the interaction between the soil system, climate and hydrology by using the soil plant atmosphere model to show how the system work as a simulation. The soil water model simulates the dynamic of water flow through a plant canopy and soil profile, infiltration and rainfall interception in the soil and evaporation and the speed of drainage of water from the plant canopy. The daisy model is able to treat an absolute number of soil profiles or soil layers specially soil dept and soil types. The daisy model output gives the result relating to soil dynamic systems as water flow. 1. The water dynamic flow above the ground 2. The water dynamic flow below the ground All the results compares base on real temperature record and estimates temperature in the future with recently found results and future results calculated by the daisy model. About our finding we divide them into 4 parts, which are finding for individual area, finding for yearly and monthly comparison between present and future, finding for comparison between different soil areas. We can see how climate change interacts with a whole system on water cycle and special on soil water dynamic system by due with soil properties and lead to another influence. Then the soil itself release the effect from the affection ( increase the releasing CO2 ) back to the climate.
