Climate of Telangana || Telangana Geography || TGPSC Exams

Main ideas and concepts (Climate of Telangana)

• Climate depends on multiple factors, including:

  • Geography
  • Insolation (sunlight input)
  • Altitude
  • Atmospheric pressure
  • Winds
  • Humidity
  • Topography

• Overall climate type

  • Telangana has a tropical monsoon climate with generally moderate conditions.
  • Hot summers and relatively cool winters.
  • Day and night lengths are approximately equal near equinoxes.
  • Telangana is located in the tropical zone in the Northern Hemisphere.
  • Being on the Deccan Plateau and landlocked limits sea moderation, affecting temperature and rainfall patterns.

• Climatic classification (Köppen)

  • The video states Telangana is mainly classified as:
    • Semi-arid
    • Humid subtropical
  • Regional distribution:
    • Northern Telangana: humid subtropical
    • Southern Telangana: semi-arid

• Key climatic features

  • Hot summer
  • Cold, dry winter
  • Rainfall mostly during the southwest monsoon
  • Rainfall varies considerably across the state (generally increases northward)
  • Very high summer temperatures; May is typically the hottest month
  • Strong influence of monsoon winds

• Important rainfall figures (as stated)

  • Average annual rainfall: ~906 mm
  • Southwest monsoon contribution: ~80%
  • Southern Telangana rainfall: ~700–900 mm
  • Northern Telangana rainfall: ~900–1500 mm
  • Mentioned: 2023–24 annual normal rainfall as 994.8 mm (also references 906 mm earlier)

• Seasons (as divided by the India Meteorological Department)

  • Winter: Dec–Feb
  • Summer: Mar–May
  • Southwest monsoon rainy season: Jun–Sep
  • Retreating northeast monsoon: Oct–Nov

• Wind systems

  • Southwest winds (humid winds): bring the major share of rainfall
  • Northeast winds (dry winds): associated with the retreating monsoon period

Detailed: Rainfall mechanisms and distribution

Southwest monsoon period (core rainfall season)

• Timeframe: June to September
• Role: most important rainfall source for Telangana

• Contribution: about 80% of total rainfall comes from the southwest monsoon

• Monsoon onset and coverage (as described)

  • Monsoon influence begins during the first/second week of June
  • By the end of June, it generally covers the entire state

• Northward rainfall increase

  • Rainfall increases from south to north
  • Southern Telangana: ~700–900 mm
  • Northern Telangana: ~900–1500 mm

• Rainfall drivers (as stated)

  • Low pressure systems originating from the Bay of Bengal influence rainfall
  • Convectional rainfall
    • Strong heating during the hot season causes air to rise
    • Moist air rises and forms cumulonimbus clouds
    • Produces thunderstorms and strong wind gusts
  • Pre-monsoon unseasonal rains (locally called):
    • “Destroying rains”
    • “unseasonal rains”
    • “Akal pani”
  • Thunderstorms and convectional rainfall are particularly linked with May

Retreating (northeast) monsoon period

• Timeframe: October to November
• Role: transition between rainy season and dry winter

• Rainfall causes

  • Mainly cyclones and low pressure systems
  • Systems from the Bay of Bengal influence rainfall

• Rainfall amount (as stated)

  • No clearly stated “normal rainfall” value for this period, but it mentions approximately 125 mm

• Possible rainfall extension

  • Telangana can receive rainfall during September–October due to low pressure systems

Rainfall distribution and variability

• General pattern: rainfall is not uniform

  • South → North: rainfall increases

• High rainfall area mentioned

  • Sileru basin as an important high rainfall receiving area

• District-wise points mentioned (under southwest monsoon / general rainfall discussion)

  • Mulugu: highest rainfall under southwest monsoon
  • Nagarkurnool and Jogulamba Gadwal / Alampur region: lower rainfall areas under southwest monsoon
  • Adilabad: relatively high rainfall compared with some other regions
  • Mahbubnagar: important low rainfall / variable rainfall region

• Rainfall instability (variability)

  • Southwest monsoon rainfall instability: more than 25%
  • Northeast monsoon rainfall instability: around 80%
  • Instability is especially significant in southern Telangana
  • Districts listed as affected by rainfall variability:
    • Mahbubnagar, Nagarkurnool, Jogulamba Gadwal, Nalgonda, Suryapet

• Impact on agriculture

  • Telangana agriculture depends heavily on seasonal rainfall
  • Uneven rainfall → agricultural uncertainty
  • Excess rainfall → flooding/waterlogging
  • Deficient rainfall → drought-like conditions
  • Therefore, the southwest monsoon is crucial for agriculture production

Detailed: Temperature and seasonal temperature features

Summer (Mar–May)

• General pattern

  • Temperature gradually increases from March
  • May is the hottest month

• Day/night contrast

  • Hot days and comparatively cooler nights

• Temperature extremes (as stated)

  • High temperatures often reach 40–43°C or more
  • Extreme heat events: places may approach or exceed 48–50°C

• Areas mentioned as important high-temperature locations

  • Ramagundam, Nizamabad, Kamareddy, Bhadradri Kothagudem, Khammam, Jagtial

• Ramagundam (highlighted)

  • Particularly important in Telangana climatology
  • Associated with very high temperatures
  • Meteorological station mentioned as serving Peddapalli, located at Ramagundam

• Urban heat effect (Hyderabad)

  • Hyderabad is comparatively warmer due to:
    • urbanization
    • increased vehicular traffic
    • cutting of trees
  • Urban areas can experience stronger heat than rural areas

Winter (Dec–Feb)

• General pattern

  • Generally dry and cold winds, especially at night
  • Temperature falls considerably in some northern and interior regions

• Example low-temperature mention (as stated)

  • Sangareddy and Ramagundam can experience temperatures below 13°C in December

• Specific low-temperature entries mentioned (Telangana Statistical Abstract 2021)

  • Kohir Mandal (Sangareddy): 2°C (as stated)
  • Lingapur Mandal (Komaram Bheem): 2.4°C (as stated)
  • Manoor Mandal (Kamareddy): 2.5°C (as stated)

Highest temperature record (as stated)

• Highest temperature mentioned: 48.9°C in May 2015

• Places listed with highest temperature record (as stated)

  • Ghanapur (Jayashankar Bhupalpally District) — 48.9°C
  • Chintalapaliem (Suryapet) — 48.9°C
  • Dhanpally (Mancherial) — 48.9°C
  • Modalpally (Nalgonda) — 48.9°C (and/or other locations listed with that figure in the subtitle sequence)

Sources/measurements and meteorological stations (as stated)

• The video mentions eight meteorological stations used for recording temperatures, located at:
  • Hyderabad, Warangal, Nalgonda, Mahbubnagar, Khammam, Nizamabad, Medak, Ramagundam
• It specifically connects Ramagundam to the meteorological station serving Peddapalli district.

---

Relationship between climate and agriculture (core lesson)

• Rainfall is the most important climatic factor for Telangana because agriculture depends on seasonal rainfall.
• Rainfall variability creates instability in agricultural output:
  • flooding/waterlogging with excess rainfall
  • drought-like conditions with low rainfall
• The southwest monsoon is emphasized as the key for agricultural production.
