Climatology deals with the study of the climate and
its effects on human health and various economic sectors.
Climate is subject to inherent variability. During the
last century, however, human activity has considerably
altered the chemical composition of our atmosphere and
a direct result is an increasing greenhouse effect.
The study of consequent climate changes is a new area
of investigation for climatology.
NIM now has climate observations that date back to the
early 20th century. After collection and validation,
the data is processed and stored. All data from 1950
onward is available on magnetic support. Such climate
database is managed by an information system that comprises
software and analysis tools so as to enable internal
and external users to use NIM climate data. The database
will thus provide users with the desired information
in the shortest time possible.
Analysis of the principal climate elements (temperature,
precipitation, moisture, evaporation, etc.) has made
it possible to identify the major climate features of
our country. Other research activities concerning the
climate trends in Tunisia during the previous century
are also in progress.
Applied meteorology is the use of meteorological data
to elaborate useful products (bulletins and specific
studies) destined to the various sectors of economic
activities particularly agriculture and hydrology.
It can provide helpful assistance to:
agriculture and farming.
irrigation planning and management.
fight against diseases and natural disasters (drought,
frost, hail, forest fire, etc.).
Hydrometeorology It can
be of helpful assistance to the various domains of hydrology.
provide basic data for hydraulic works (sanitation,
dams, drainage, etc.).
contribute to elaborate statistics for rain.
