|Abstract. This article proposes a methodology to discover patterns in observed
climatologic data, particularly temperatures and rainfall, in
subnational political division units using an automatic classification
algorithm (a decision tree produced by the C4.5 algorithm). Thus, the
patterns represent classification trees, assuming that: (1) every
political division unit contains at least one climatological station,
and (2) the recording periods of the stations are relatively similar in
duration and in their initial and ending years. A series of
classification models are produced by using different subsets from an
experimental dataset. This dataset contains information from 3606
climatological stations in Mexico with recording periods whose
durations, initial and ending years are diverse. The target (dependent)
variable in all these models is the name of the political unit (i.e.,
the state). The predictors are 36 monthly features per each
climatological station: 12 features corresponding to a minimum
temperature, 12 to a maximum temperature, and 12 to cumulative rainfall.
The altitude feature is also used as one of the predictors, in addition
to the other 36; however, it is used only to quantify its additional
contribution to the modelling. The results show that classification
trees are effective models for describing and representing non-trivial
patterns to characterize the political division units based on their
monthly temperatures and rainfalls. One of the remarkable findings is
that the cumulative rainfall of May is the feature with highest
discrimination capability to the characterization task, which is
consistent with the theoretical background on Mexican climatology. In
addition, classification trees offer higher expressivity to non-experts
in machine learning.
