WMO Tropical Cyclone Program
1972: WMO establishes the Tropical Cyclone Project
in response to a call for international action to
mitigate the harmful effects of tropical cyclones
brought about by the disastrous 1970 Bangladesh
storm.
1978: A second working group, that of WMO's
Regional Association for North, Central America and
the Caribbean, (RA IV) - the Hurricane Committee -
was established.

Dvorak technique
The Dvorak technique (developed between 1969 and 1984 by
Vernon Dvorak) is a method using enhanced Infrared and/or
visible satellite imagery to quantitatively estimate the intensity
of a Tropical Cyclones

Summary
• Exchange of weather information to make regional
synoptic charts.
• Establishment of the World Meteorological
Organization to further coordinate the exchange of
weather information and capacity building
• Satellite Images became available in the 1960s
• Hurricane Hunter missions became Hurricane
Reconnaissance missions
• Techniques to analyze satellite images
• Enhancement of the Early Warning System
