1. Cloudburst Forecast in India

Syllabus: Atmospheric Circulation & Weather Systems

Mains: Significance of relevant meteorological forecasting for better disaster management.

Context: A cloud burst incident in the Lasko river flowing close to the India and Nepal border in Uttarakhand has resulted in significant damages to life and property.

What are Cloudbursts?

  • Cloudbursts are sudden, violent and voluminous amounts of rain in a short durationΒ  that is local in nature.Β 
  • Cloudbursts are defined by the amount of rainfall. According to the India Meteorological Department (IMD), 100 mm of rain in an hour over a region of 20 to 30 square kmΒ  is called a cloudburst.Β 
  • Cloudburst is defined as a geo-hydrological hazard due to their aggressive nature and the scale of destruction.
  • In India, cloudburst occurs during the time of the South-West Monsoon from the month of June.Β 
  • Cloudburst is difficult to predict since it occurs suddenly with a catastrophic force and thereby inflicts enormous losses due to inundation and erosion.

Prone Areas:

  • Cloudbursts occur mostly over the rugged terrains over the Himalayas, the Western Ghats, and northeastern hill States of India due to orographic lifting together with a strong moisture convergence that can lead to intense cumulonimbus clouds taking in huge volumes of moisture.

  • The heavy rainfall on steep slopes trigger landslides, debris flows, and flash floods, causing significant destruction and loss of people and property.
  • Recent cloudbursts that caused significant devastation occurred over the Himalayan foothills, northeastern States and Western Ghats States.
  • Strong monsoon wind surges along the coast can also result in cloudbursts, as in the case of Mumbai (2005) and Chennai (2015).Β 
  • Coastal cities are particularly vulnerable to cloudbursts since the flash floods make the conventional stormwater and flood management policies in these cities dysfunctional.
  • Climate change is projected to increase the frequency and intensity of cloudbursts as the air gets warmer, it can hold more moisture and for a longer time.Β 
  • A one-degree Celsius rise in temperature may correspond to a 7-10% increase in moisture and rainfall and this increase in rainfall does not spread moderately throughout the season.

Cloudburst forecasting in India: Why it is a challenge

  • The IMD’s forecasts are at an advanced stage with respect to extreme rains and cyclones. However, cloudburst forecasts still remain elusive and our efforts in monitoring and forecasting them are at the early developmentalΒ  stage.Β 
  • Monitoring stations on the ground can hardly capture the cloudburst characteristics due to their highly localised and short occurrence.Β 
  • The resolution of the precipitation radars of weather satellites can be much smaller than the area of individual cloudburst events, and hence they go undetected.Β 
  • The skillful forecasting of rainfall in hilly regions remains challenging due to the uncertainties in the interaction between the moisture convergence and the hilly terrain, the cloud microphysics, and the heating cooling mechanisms at different atmospheric levels.Β 
  • Multiple doppler weather radars can be used to provide forecasts for the next three hours but they are an expensive affair, and installing them across the country may not be practically feasible.Β 

Way Forward:

  • Cloudburst-prone regions should be mapped using automatic rain gauges.Β 
  • If cloudburst-prone regions are co-located with landslide-prone regions, these locations can be designated as hazardous.
  • With IMD enhancing its automatic weather stations, we may have hourly data that can help map cloudburst-prone regions.Β 
  • People in risk prone areas should be moved, and construction and mining in nearby regions should be restricted as that can aggravate the landslides and flash flood impacts.

Nut Graf: Cloudbursts are reported frequently from across the country. Most of these events go unreported due to the lack of monitoring mechanisms,weakening our ability to understand these events in complete perspective. Immediate actions and policies to protect lives and property from cloud bursts is the need of the hour as these events will amplify with rise in global temperature.

F. Prelims Facts

1. Exercise Parvat Prahar

Syllabus:Β  Various Security Forces & Agencies & Their Mandate

Prelims: Military Exercise

Context: Recently, Army chief General Manoj Pande visited the Ladakh sector to review Exercise Parvat Prahar.

Key Details:

  • The exercise saw the deployment of all new major inductions of the Army.
  • The exercise was held in the Ladakh plateau at an altitude of 14,000 feet.
  • The army used newly inducted all-terrain vehicles transported by Chinook heavy lift helicopters and K9-Vajra howitzers, among others.Β 
  • The exercise featured a display of operational capabilities by artillery guns and other key weapon systems.Β 
  • The exercise comes as India and China are undertaking disengagement from Patrolling Point-15 in eastern Ladakh.

1. Railways and Detonators

  • The Indian Railways is considering withdrawing a decades-old policy of guards protecting the rear of the train stopped at home signal using explosives to prevent a collision.Β 

Working of a railway detonator:

  • Railway detonator was invented in 1841 by English inventor Edward Alfred Cowper.
  • It is a coin-sized device that is used as a loud warning signal to train drivers which is placed on the top of the rail, usually secured with two lead straps, one on each side.Β 
  • When the wheel of the train passes over, it explodes, emitting a loud bang.

Detonators in Indian Railways:

  • Passenger and freight trains being stopped at the home signal ahead of railway stations is a usual practice owing to operational reasons like the availability of line for the incoming train.Β 
  • However, when the detention of such trains exceeds 15 minutes, the general rules for Indian Railways prescribe for the guard to protect the rear of the train from any possible collision by a train approaching from behind.Β 
  • The guard is duty-bound to place detonators at certain distances that will trigger multiple minor explosions with a loud noise when a train passes on them giving an alert to the loco pilot of obstruction ahead.

    • VoLTE stands for Voice over Long Term Evolution. Like LTE, it also holds 4G networks, and you can enjoy the high-speed internet service with it. Even with VoLTE, you can enjoy voice calling with data service.
  • Statement 02 is incorrect, under LTE, the infrastructure of telecom players only allows transmission of data while voice calls are routed to their older 2G or 3G networks.Β 
    • VoLTE is both data and voice technology. Basically VoLTE systems convert voice into the data stream, which is then transmitted using the data connection.
