occasionally also known as wet seasons or trade-wind littoral seasons, are
found in the regions where
there is a complete seasonal reversal of the prevailing surface winds.
Accompanying these shifts in the prevailing surface winds are modulations in
rainfall activity. Given the fact that our knowledge of the monsoons is mainly based on the interpretation of the
mean values of precipitation, cloudiness and winds; relationships between
earth’s rotation or revolution and geographical extent of the global surface
monsoons deserve to be highlighted. In the abundant literary and audiovisual
production devoted to monsoons worldwide and despite the fact that everyone
agrees with physical law which shows that Coriolis force acts to the right in
the northern hemisphere (to the left in the southern hemisphere), there is no
reference to the relationship between Coriolis force (due to earth’s rotation)
effects on troposphere general circulation and geographical extent of the
global surface monsoons. Furthermore knowing that the ITCZ oscillations on
either side of the equators (due to
earth’s revolution) determine the seasons (mainly winter and summer), it is
clear that earth’s revolution also plays a crucial role in the seasonal reversal of the prevailing surface
winds observed in the regions where monsoons are found. Our main objective is
to provide a rational answer to the question: what is a monsoon?
Mbane Biouele formula derived in 2009 on the troposphere thermoelastic
properties leads to thermal and kinematic profiles of major atmospheric
disturbances which clearly indicate that these terrible events for men should
not be viewed with fatalism. This unexpected truth is unfortunately always
obscured by media outlets of brilliant TV presenters or famous workshops
panelists that focus attention on the excessively sensational meteorology
(unfortunately folk and pernicious) instead of worrying about the seriousness
that should characterize all interventions on the climate study or prediction.
Good weather conditions, it is undeniable, facilitate an excellent running of
almost all human activities like sports, transport, agricultural activities,
celebrations of events, etc.... Far more serious, the advent of supercomputers and satellites could, if their valuable information is used solely for
the theatricalization of weather events, trigger the decline of the scientific
discipline of great public utility that is meteorology. Indeed, many meteorologists
acquire very big head when they succeed in acquiring advanced equipment.
Without prejudging what meteorology will become in the future, we hope that the work done in this article
will remind each researchers that much remains to be done to promote climate
studies. We remind quite emphatically that both hurricanes and cyclones have
their weak-points (or talon d’Achilles in French) and thus, researchers should begin to think about “how to neutralize atmospheric disturbances that
have both a large and a strong destructive power”.
