wind speed,
hurricane size, and forward speed (whether it stalls or not) to rate the potential destructiveness of a storm 1 - to - 10
scale.
Weevils have attacked the plants in the past, damaging the local crop, but the biggest threats to supply are the lack of large -
scale producers (most locals just grow a few plants for their own use) and
hurricanes, which dump heavy rains and pack a punch with fierce
winds that destroy the fragile plants.

wind, the air - water interface was producing projectiles fragmenting into sub millimeter
scale water droplets.
Despite consistently warm waters, tropical cyclones in the Arabian Sea typically don't reach the higher end of the
hurricane scale because
winds in the upper atmosphere tend to cut them off.
My speculation —
wind shear defusing
hurricanes but pumping up tornados — didn't seem apt, the size /
scale is so different between the two kinds of storms that
wind shear means something different for each type.

The colour field underneath the
wind arrows shows the precipitation rate on a
scale from 0 to 20 mm per hour, noting that peaks in rainfall intensity (which may have been far higher than 20 mm / hr at times in localised regions within the

Once a
hurricane develops, it is classified with the Saffir - Simpson
