Abstract EN

Habitually, the monthly type models are defined by using the most dominant characteristics that characterize their Climatic "forms'.

This methods help in defining the similar and the different climatic forms and lead to real and scientific diagnosis of the real geographical seasons on Earth.

The mean temperature and the mean humidity elements are usually used to identify the monthly type models of climate.

These elements, in fact, are the most important in characterizing the monthly climatic models in KSA and other climatic regions worldwide.

The problem of this research deals with the role of prevailing daily wind directions in defining the monthly type models of climate in KSA.

The wind daily directions allow the identification of the total interactions of the isobaric units/centers over a region.

The pattern of these daily changing interactions generates new and distinct weather models.

Hence, the use of the prevailing wind daily directions means the reliance on the real monthly climatic structure that generated on daily manner in order to classify their climatic similarities.

Finally, the monthly means will be not being considered as a main element in this classification.

Rather the monthly climatic structure will be depended upon using the modern quantitative methods such as HOMLAS
