from a subtle swirl in the sky to a
0:02
monstrous churning vortex with the power
0:04
to level cities every hurricane begins
0:07
somewhere what causes this
0:09
transformation what hidden forces propel
0:11
a calm system into a deadly cyclone the
0:14
journey of these storms from weak
0:16
tropical depressions to powerful
0:18
hurricanes or typhoons and cyclones
0:20
depending on the region is a fascinating
0:23
process that underscores the immense
0:24
complexity and power of nature
0:27
understanding these stages is not just
0:29
an academic pursuit it's a vital key to
0:31
preparedness and survival tropical
0:34
cyclones form over warm ocean waters
0:36
where sea surface temperatures provide
0:38
the energy needed to kickstart the storm
0:41
the process begins with a tropical
0:43
disturbance clusters of thunderstorms
0:45
over warm seas if atmospheric conditions
0:48
are favorable such as low wind shear and
0:50
high humidity the disturbance may begin
0:52
to organize and a low pressure center
0:56
when this low pressure system exhibits
0:58
sustained winds of up to 38 mph 62 km
1:02
hour it is classified as a tropical
1:05
depression though weak this early stage
1:08
is critical the system starts to show
1:10
signs of rotation and becomes more
1:12
organized if favorable conditions
1:15
persist especially warm ocean water
1:17
fueling continuous evaporation and
1:19
convection the storm can strengthen
1:21
further once sustained winds reach
1:24
between 39 and 73 mph 63 to 118 km per
1:29
hour the storm becomes a tropical storm
1:32
at this point the system is given an
1:34
official name it begins to develop more
1:37
defined features like spiral rainbands
1:39
and a tighter core while less
1:42
destructive than a full hurricane
1:44
tropical storms can still produce
1:45
torrential rains flooding and strong
1:48
winds that impact coastal and inland
1:50
areas when wind speeds exceed 74 mph 119
1:55
km per hour the system is classified as
1:58
a hurricane in the Atlantic and
2:00
Northeast Pacific a typhoon in the
2:02
Northwest Pacific or a cyclone in the
2:04
South Pacific and Indian Ocean these
2:07
mature tropical cyclones exhibit a well-
2:09
definfined eye eyewall and powerful
2:12
rainbands they are capable of
2:14
devastating infrastructure disrupting
2:16
lives and costing billions in recovery
2:19
understanding the development stages of
2:21
these storms empowers us to respond
2:23
earlier and more effectively the earlier
2:26
a storm is tracked and its potential
2:28
recognized the more time communities
2:30
have to prepare and adapt in an era of
2:33
intensifying storms due to climate
2:35
change this knowledge could make all the
2:37
difference between safety and
2:39
catastrophe have you ever followed the
2:41
life of a storm from its earliest
2:43
formation what surprised you most about
