Situs Tunjukkan Cara Hindari Tsunami Donny Andhika ( istimewa ) INILAH.COM, Jakarta- Sebuah website pendidikan telah dioperasikan untuk membantu orang-orang agar siap menghadapi serangan tsunami. Situs itu dikembangkan oleh Institut Oceanografi Wood Hole. Dijuluki dengan petunjuk interaktif yang dapat menyelamatkan hidup anda, situs tersebut juga menampilkan hasil riset sains terakhir yang berhubungan dengan tsunami, serta video dari para korban yang selamat, lengkap dengan wawancara. “Tsunami tidak bisa dicegah atau diperkirakan," kata Lin Jian, pengagas situs. Ia juga seorang ahli geologi Woods Hole yang secara aktif terlibat dalam penelitian tsunami, serta anggota komite nasional AS untuk peringatan tsunami dan kesiagaan. "Orang yang mengetahui tentang tanda-tanda peringatan tsunami dapat menyelamatkan hidup mereka sendiri dan kehidupan orang lain." Tsunami berasal dar...

In the ensuing study, the ocean has a function to stabilise the surface temperature of the Earth due to its ability to organise latent heat and to perform as the dominant source of atmospheric moisture and the spatial distribution of the moisture flux to the atmosphere are controlled by SST as was explained in many text books (e.g. Duxbury et al. , 2002; Tomczak and Godfrey 2003). To take an example, in previous work, Nicholls (1981, 1984) shows that air-sea interaction in Indonesia is related to SST anomalies and it has a strong seasonal relation with Pacific Ocean. The above description gives a clear argument that SST is the principal oceanic parameter for the atmosphere. Next question arises, how does the mechanism generating the SST? The mechanisms that generate and maintain SST within Indonesian seas are consequence of the complex topography and connectivity between the Pacific and the Indian Oceans (Qu et al., 2005). The SSTs across the Indonesian region are importance ...

`How do we Understand Sea surface temperature and rainfall variability in the Indonesian region?’ The Indonesian seas located at the confluence of the Eurasian Plate, the Indo-Australian Plate and the Pacific Plate. The area is comprises shelf in the west part and deep sea in the east part with their spatial characteristics. Moreover, the Indonesian archipelago is also known as the ‘Maritime Continent’ that is composed of more than 17,000 islands (Ramage 1968; Qu et al . 2005, Smith and Sandwell, 1997). Since the early comprehensive review of Pariwono (1986) on Indonesian waters and some papers (Pariwono, et al. , 2005, van Aken, 2005), the subject has not been specifically the combination between ocean and atmospheric phenomenon (e.g. Hendon, 2003; Qu, et al . 2005). This introductory review is a contribution to fill in this gap, but is by no means exhaustive. Furthermore, the essay is intended to overview sea surface temperature and rainfall variability in the Indones...

The sea surface temperature anomaly (SSTA/ deviation from normal ) is the difference between the observed SST and the climatological SST. These anomalies are calculated on a weekly basis. Positive SSTAs are usually correlated with increased regions of convection (cloudiness and rainfall) while negative SSTAs are usually correlated to reduced convection. SSTAs can be used as an indicator of the phase of global climate fluctuations, such as the El Nino/Southern Oscillation (ENSO). S ea Surface Temperature anomalies in degrees Celsius, or "SST anomalies" for short, are how much temperatures depart from what is normal for that time of year. This makes sense; we might say that we had a "warm winter" even though it was still much colder than summer. What we mean is that it was warmer than a normal winter; in our parlance, we would say that it was a "positive anomaly". An unusually cold winter would be a "negative anomaly". For Pacific SST, an anomaly...
