Bayesian Convolutional Neural Network (BCNN)
Syllabus: GS1/Geography;
Context
- Recently, Indian National Centre for Ocean Information Services (INCOIS) has developed the Bayesian Convolutional Neural Network (BCNN) to predict the emergence of El Nino and La Nina conditions up to 15 months in advance.
About the Bayesian Convolutional Neural Network (BCNN)
- It is cutting-edge technology that harnesses the power of Artificial Intelligence (AI), deep learning, and machine learning (ML) to enhance predictions related to the El Niño-Southern Oscillation (ENSO) phases.
- The BCNN model is particularly adept at predicting El Nino or La Nina events due to its ability to account for the slow oceanic variations and their atmospheric coupling.
- It calculates the Nino3.4 Index Value, a critical metric used in ENSO phase prediction, with improved precision which is obtained by averaging the sea surface temperature (SST) anomaly in the central equatorial Pacific, extending from 5°N to 5°S, and 170°W to 120°W.
- It offers a promising future for more reliable and timely weather predictions, which are vital for agriculture, fisheries, and disaster management.
- It is a combination of the dynamic model with AI that helps it forecast the emergence of El Niño and La Niña conditions with a 15-month lead time — unlike other models which can give a prediction up to six to nine months in advance.
INCOIS – It was established as an autonomous body in 1999 under the Ministry of Earth Sciences (MoES) and is a unit of the Earth System Science Organisation (ESSO). – It is mandated to provide the best possible ocean information and advisory services to society, industry, government agencies and the scientific community through sustained ocean observations and constant improvements through systematic and focussed research. Weather Models – There are largely two kinds of weather models used for forecasting, ie: – Statistical Model: It generates forecasts based on various information sets received from different countries and regions – Dynamic Model: It involves a 3D mathematical simulation of the atmosphere done using High Performance Computers (HPC). a. It is much more accurate than the statistical model. |
El Nino-Southern Oscillation (ENSO) – It is a climate phenomenon which involves changes in the temperature of waters in the central and eastern tropical Pacific Ocean, coupled with fluctuations in the overlying atmosphere. a. It can alter the global atmospheric circulation, which, in turn, influences weather across the world. – It occurs in irregular cycles of 2-7 years and has three different phases — warm (El Nino), cold (La Nina), and neutral. b. Neutral Phase: The eastern side of the Pacific Ocean (near the northwestern coast of South America) is cooler than the western side (near the Philippines and Indonesia). This is due to the prevailing wind systems that move from east to west, sweeping the warmer surface waters towards the Indonesian coast. The relatively cooler waters from below come up to replace the displaced water. c. El Nino (Warm Phase): Wind systems weaken, leading to lesser displacement of warmer waters. As a result, the eastern side of the Pacific becomes warmer than usual, and trade winds — east-west winds that blow near the Equator — weaken. Normally, easterly trade winds blow from the Americas towards Asia. Due to El Niño, they falter and change direction to turn into westerlies, bringing warm water from the western Pacific towards the Americas. d. La Nina (Cold Phase): La Nina is the opposite of El Nino. It is cooler than average sea surface temperature (SST) in the equatorial Pacific region. Trade winds are stronger than usual, pushing warmer water towards Asia. – In India, while El Nino conditions usually lead to a weak monsoon and intense heat waves, La Nina conditions result in a strong monsoon. |
