DISCUSSION
1.
The Committee at its twentieth session (Maputo, Mozambique, 3 to
7 September 2012) carried out a detailed review of the Operational Plan and recommended
to the President of RA I the amendments to the text of the Plan, for approval on behalf of the
Association.
2.
In response to the request of the Committee, the 2012 Edition of the Plan based on
the updated text approved by the President of RA I was issued under a WMO number
(WMO/TC-No. 577) in English and French.
3.
The Operational Plan defines the sharing of responsibilities among Members for the
various segments of the system and records the high level of regional cooperation and
coordination achieved. In particular, it records the agreed arrangements including, amongst
others, those for standardization of operational procedures, provision and efficient exchange
of various data related to tropical cyclone warnings and issue of tropical cyclone advisories,
and other products from a central location, i.e. RSMC La Réunion with activity specialization
in tropical cyclone analysis, tracking and forecasting, which has the required facilities for this
purpose.
4.
In reviewing the Operational Plan, it is proposed to take into account the particularly
important role of the RSMC La Réunion and Sub-regional Tropical Cyclone Advisory
Centres.
5.
Members are invited to submit a list of names (both male and female) for tropical
cyclone disturbances having at least moderate tropical storm intensity to be used in the
region for the seasons 2015/2016, 2016/2017, 2017/2018 and 2018/2019, for discussion at
this session.
