Mosquito-borne diseases particularly malaria is becoming most dreaded health problems in the Coastal Blocks of Ramanathapuram District, Tamilnadu, India. In Coastal Blocks of Ramanathapuram District, malaria is seasonal and unstable, causing frequent epidemics. For transmission of malaria parasite, climatic factors are important determinants such as rain fall, temperature relative humidity and ...

Throughout the 1960's and 1970's, oceanographers referred to the large-scale warming of the equatorial eastern and central Pacific as El Nino. This anomalous warming was later shown to be associated with anoma­ lies in the upper ocean thermal structure throughout the equatorial Pacific Ocean. At about the same time, scientists realized that the Southern Oscillation was in­ timately related to t...

[1] The probability distribution function (PDF) of the upper (0–50 m) tropical Pacific current speeds (w), constructed from hourly ADCP data (1990–2007) at six stations for the Tropical Atmosphere Ocean project, satisfies the twoparameter Weibull distribution reasonably well with different characteristics between El Nino and La Nina events: In the western Pacific, the PDF of w has a larger peak...

ABSTRAKKabupaten Muaro Jambi merupakan kabupaten di Provinsi dengan luas karhutla terbesar 4.054 hektar (34,55%). Hal ini dikarenakan sebagian besar jenis tanah Kabupaten gambut. Pada penelitian bertujuan untuk melihat hubungan antara parameter cuaca dan distribusi titik panas Jambi. Parameter yang akan dianalisis yaitu curah hujan pada tahun 2019 2020 dimana mewakili terjadinya El Nino tanpa N...

The impact of climate variability on the water cycle in desert ecosystems is controlled by biospheric feedback at interannual to millennial timescales. This paper describes a unique field dataset from weighing lysimeters beneath nonvegetated and vegetated systems that unequivocally demonstrates the role of vegetation dynamics in controlling water cycle response to interannual climate variabilit...

[1] We used the approach of conditional nonlinear optimal perturbation (CNOP) to investigate optimal precursors for El Nino–Southern Oscillation (ENSO) events with a theoretical coupled ocean-atmosphere model. The CNOPs of the annual cycle of the coupled system were computed for different time periods, and the derived CNOPs were compared with the linear singular vectors (LSVs). The results show...

In the summer following a strong El Nino, tropical cyclone (TC) number decreases over the Northwest (NW) Pacific despite little change in local sea surface temperature. Our analysis suggests El Nino-induced tropical Indian Ocean (TIO) warming as the cause. The TIO warming forces a warm tropospheric Kelvin wave that propagates into the western Pacific. Inducing surface divergence off the equator...

Great progress has been made in the effort to understand and predict El Nino, the anomalous warming of the sea surface temperature (SST) along the equator off the coast of South America which has a strong impact on the climate change over the world. Advances in improved climate predictions will result in significantly enhanced economic opportunities, particularly for the national agriculture, f...
