especially on the hydrometeorological
phenomena
using
space
technology
applications. Firstly, we reviewed the basic
concept of global climate change based on the
trend of surface temperature and precipitation
over several regions over Indonesia. Since the
Indonesia Maritime Continent (IMC) is mostly
effected by the dynamical of Monsoon system,
we mainly focussed on the flood and
drought hazard.

Since
both phenomena is related well to agriculture
sector, we need to consider to save the elevent
provinces that has already stated as the rice
production center from the extreme weather

Here,
we promote

SADEWA (Satellite Disaster Early Warning
System) and the equatorial atmospheric model
that still developing by LAPAN Bandung.
“Regarding to the statement from the
IPCC experts who stated that as a result of
climate change, more frequent and more
yd o eteo o og ca events
intense hydrometeorological
can be expected, we mainly concerned to
investigate the surface temperature and
precipitation (rainfall) behavior over Java
Island, including their trend or tendency
taken from satellite and in-situ
observation respectively”

From this figure,
figure we can see,
see at least we have
seven climate hazards over Indonesia. They
are :
1. Earthquake
2 Vulcano
2.
3. Tsunami
4 Tropical Storm

5. Storm Surge
. Flood --- > much water
7 Drought --- > less water

We know that both phenomena (flood
and drought) is related well with the
anomaly of Monsoon system, but we
need to consider the other phenomena
that also have severe impact that we call
as the MJO (Madden Julian Oscillation) as
one of the most mode oscillation along
the equatorial region. We can see Jakarta
flood’s in 1996, 2002, 2006, 2007, and
2013 recently as the samples the severe
impacts of MJO event in the Western part
of Indonesia region.

Definitions of climate change
(IPCC, AR-4, 2007)
Climate change in IPCC usage refers
to a change in the state of the
climate that can be identified (e.g.
using statistical tests) by changes in
the mean and/or the variability of its
properties and that persists for an
properties,
extended period, typically decades
or longer.
