Hydrological rhythm refers to the periodic and rhythmic changes of lake water regime. The generalized hydrological rhythm includes circadian, monthly, seasonal and interannual rhythms. Under normal circumstances, due to the relatively stable factors such as watershed climate and underlying surface, the multi-year average water level of the lake tends to be stable, that is, the normal annual average water level of the lake. Therefore, the interannual rhythm of lakes is characterized by the mutation driven by interference factors and the stage stability after adapting to interference, and there is no gradual trend; the circadian rhythm has little impact on the ecosystem. Therefore, the narrow hydrological rhythm refers to the monthly and seasonal rhythm.
According to the above definition, which one of the followings belongs to the narrow hydrological rhythm?
The historical average annual water temperature of Hongze Lake is 16.3.
