WMO Confirms El Ni o Onset: Global Extreme Weather Warning Issued
The UN's weather agency has confirmed the start of El Ni o, warning of widespread extreme weather and above-average temperatures globally.
Source: UN NewsThe World Meteorological Organization (WMO) officially confirmed the onset of El Ni o on Tuesday. This natural climate phenomenon involves the warming of surface waters in the central and eastern tropical Pacific Ocean. The WMO warned that El Ni o will lead to above-average temperatures across nearly all parts of the world. It is also expected to fuel more extreme weather events globally. The United Nations urged all countries to strengthen their early warning systems in response to this confirmation. This move aims to help nations prepare for and mitigate the impacts of the anticipated severe weather conditions. The WMO's announcement highlights the need for increased readiness and adaptation strategies worldwide.
This news is crucial for competitive exams, especially for UPSC GS Paper I (Geography) and GS Paper III (Environment & Disaster Management), and SSC General Awareness. El Ni o is a significant climate driver impacting global weather patterns, agriculture, and disaster preparedness. Aspirants should understand its causes, effects, and the role of international organizations like WMO in monitoring such phenomena. It links to topics like climate change, oceanography, and international cooperation on environmental issues.
- The World Meteorological Organization (WMO) confirmed the onset of El Ni o.
- El Ni o involves the warming of surface waters in the central and eastern tropical Pacific Ocean.
- The phenomenon is expected to cause above-average temperatures 'nearly everywhere' globally.
- It is also predicted to fuel more extreme weather events worldwide.
- The United Nations urged countries to bolster early warning systems.
- El Ni o typically occurs every 2 to 7 years and lasts for 9 to 12 months.
El Ni o is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean. It is the warm phase of the larger El Ni o-Southern Oscillation (ENSO) phenomenon. El Ni o can have significant impacts on weather patterns, ocean conditions, and marine life around the world, often leading to increased rainfall in some areas and droughts in others.
The WMO is a specialized agency of the United Nations responsible for promoting international cooperation on atmospheric science, climatology, hydrology, and geophysics. Founded in 1950, its headquarters are in Geneva, Switzerland. The WMO provides authoritative scientific assessments and services related to weather, climate, and water, supporting disaster risk reduction and sustainable development.
La Ni a is the counterpart to El Ni o, representing the cooling of ocean surface temperatures in the central and eastern tropical Pacific Ocean. It is the cold phase of the El Ni o-Southern Oscillation (ENSO). La Ni a typically brings opposite weather impacts to El Ni o, such as increased rainfall in Southeast Asia and drier conditions in parts of the Americas.
UPSC often asks about the causes and effects of El Ni o and La Ni a, their impact on Indian monsoon, and related international efforts. SSC exams may focus on definitions and the role of organizations like WMO.
Remember 'El Ni o' as 'The Boy' (Spanish for boy), bringing 'warm' and 'wild' weather, while 'La Ni a' (The Girl) brings 'cool' and 'calm' conditions.
Frequently Asked Questions
What is the primary cause of El Ni o and its global impact?
El Ni o is primarily caused by a weakening of the trade winds in the Pacific Ocean, allowing warm water to spread eastward. This shift in ocean temperatures disrupts atmospheric circulation, leading to altered rainfall patterns, temperature extremes, and increased frequency of certain weather events globally.
How does El Ni o affect India's monsoon and agricultural sector?
El Ni o often leads to a weaker Indian monsoon, resulting in below-average rainfall. This can negatively impact India's agricultural sector, particularly for rain-fed crops, potentially causing droughts and affecting food security and the economy.
What is the difference between El Ni o and La Ni a?
El Ni o is characterized by the warming of surface waters in the eastern tropical Pacific, while La Ni a is characterized by the cooling of these same waters. They are opposite phases of the El Ni o-Southern Oscillation (ENSO) and typically bring contrasting global weather impacts.
