An Introduction to Agro-
meteorology
2. Introduction
Environment the aggregate of all external conditions
& influence affecting the life & development of an
organism, plays a dominate role in crop production.
Climatology: is the science that seeks to describe &
explain the nature of climate, how it differs from place
& how it is related to human activities. It deals with
average conditions representative of long term state
of the atmosphere & its variability.
Meteorology: as physics of the weather phenomena.
It specially concerned with the physics of weather
phenomena & deals with day to day atmospheric
conditions & their causes.
Greek word “Meteoro” means ‘above the earth’s surface’
(atmosphere) “logy” means ‘indicating science’. Branch
of science dealing with that of atmosphere is known as
meteorology.

3. Introduction
Agro-climatology: the science that deals with the
aspects of climatology having direct relevance to
agriculture. It seeks to relate climatic regimes to
agriculture production.
Agro-meteorology: as a science investigating the
meteorologic, climatologic & hydrologic conditions
that are significant for agriculture owing to their
interaction with the object & processes of agricultural
production.
Another definitions…..
It is a branch of meteorology that examines the effect &
impact of weather & climate on crops, livestock &
various agricultural operations.
Branch of meteorology, which investigates the
relationship of plants & animals to the physical
environment.
4. Intro………..
It is the science of meteorology to service of
agriculture for sensible use of land, accelerate
production of food & to avoid irreversible abuse of
land resources.
It is the study of response of living organisms to
the physical environment. The living organisms
are cultivated plants, livestock, insects &
microorganisms.
Task of meteorology is to apply relevant
meteorological skill to helps farmers to make
most efficient use of physical environment for
profitable crop production.
5. Importance to Crop
Helps in planning cropping patterns/systems.
Reduction in waste of capital.
Manipulation selection of sowing dates for
optimum crop yields.
Reducing losses of applied chemicals and
fertilizers.
Judicious irrigation to crops.
Efficient harvesting of all crops.
Reducing or eliminating outbreak of pests and
diseases.
Efficient management of soils which are formed
out of weather action.
6. Climate & Weather
Pertains to the day to
day state of the
atmosphere at a
particular place.
Refers to specific
instant of time to and
place.
It is always changing
& differs from time to
time.
Pertains to the
atmosphere over a
given region.
Refers to a large
region & for a long
period of time.
It is more or less
stable and differs from
region to region.
7. Scope of Agro- meteorology
Its helps in improving the crop production as it is
concerned with the interaction between
meteorological & hydrological factors on one
hand agriculture on other hand
The scope of agro-meteorology is to make use of
meteorology knowledge for sustainable
agricultural system.
