Weather and Climate of Ghana
This publication is an account of the weather and climate of Ghana
primarily designed for the agriculturalist and hence is mainly
concerned with atmospheric conditions at or near the earth's surface.
Topics discussed include
- Circulation of the atmosphere over West Africa,
- Circulation of the atmosphere over Ghana, and
- Weather Zones in West Africa
- Mean values of climatological elements such as
- Length of day, Solar Radiation, Sunshine, Cloud amount,
- Rainfall, and Temperature, for Ghana as a whole, as well as
for some specific cities and towns in the country are also provided.
- Other element considered include
- Surface Winds, Humidity,
- Evaporation, Evapotranspiration and Pressure
- Climatological Statistical Information on Weather Phenona
such as
- Line squalls Thunderstorms and
- Hail can also be found in this Publication
A large appendix of valuable climatological statistics of some
fifteen (15) towns and cities in Ghana can also be found at the
end of the publication.
Probability Distribution of Annual Rainfall in Ghana
In the realm of applied climatology, there
is constant need of predicting certain meteorological variables.
Prediction is used in a wide sense to include the ability to
make probability statements of future events.
Annual rainfall is one of the most important
climatological variables on which such prediction is required
for planning and design purpose in the field of hydrology and
agriculture. To be able to make such probability statements
successfully, the frequency or cumulative distribution of the
annual rainfall must be specified. In cases where statements
are required at a single place and on a single sample of annual
rainfall, all that may be required is to fit an empirical cumulative
distribution to the sample data. But where statements are to
be made in many places in the country, it is a great advantage
if a simple theoretical distribution can be found which fits
samples of annual rainfall from all the different places in
the country.
This publication explores the possibility of using such a simple
theoretical distribution to construct maps of annual rainfall
with specified probabilities for Ghana.
Climatic Maps of Ghana for Agriculture
The publication is specially designed to serve
general requirements on agroclimatology and contains substantial
amount of climatological data and information with emphasis
on the presentation in the form of maps, which are easy to interpret
and use.
It was undertaken in general response to many
requests from agriculturists, economists, engineers, educationists
and hydrologists for climatological information and advice for
land-use and/or economic planning and operational purpose.
A thorough knowledge of local climate and its
probable anomalies is essential for successful land-use planning
as well as economic planning. Information of this publication
could as such be afford in a wide area for planning purposed.
Maximum Rainfall Intensity-Duration Frequencies in Ghana
Today water resources planning has become so
sophisticated that it can almost be called an academic discipline
in itself like no other subject it has brought together scientists
from a variety of fields notably civil engineering, hydrology,
regional and national planning and economics.
Water resources planning takes into cognizance
not only data requirements themselves but also the relationship
between the quality of available data on the one hand and the
various planning techniques on the other hand.
The publication is designed to assist civil
engineers as well as other interested users to arrive at suitable
design criteria for the many engineering projects such as dams,
bridges, culverts, and other forms of water resources developments
that may undertaken in the country.
Mean Monthly and Annual Rainfall Maps
The following information can be found in the above publication.
- MONTHLY ISOHYETAL PATTERN - drawn from rainfall data
for the
period (1931-1960).
- ANNUAL ISOHYETAL PATTERN - have also been presented.
Annual and Monthly isohyetal patterns, drawn from data for the
period 1961-90, are also now available at the department.
Ten-day Rainfall Totals
This publication contains ten-day total rainfall amounts for
over 160 stations scattered through out the country. Copies
are available at the Department.
- Agrometeorological Bulletin
This is a monthly publication of selected climatological data
of agricultural importance.
Observed values (OBS) and the departures of these values from
the long period averages (DEP) are given for the elements except:
-
1. Relative Humidity where only observed values are given.
2. Wind Run per day in (KMS) where observations only are
given.
3. Mean Daily Evaporation Class A Pan where only observed
values are given.
4. Mean Daily Solar Radiation where reliable values are
now available.
