    Study Notes

    Overview of Pakistan's Climate

    • Climate ranges from tropical/subtropical in the lowlands to cooler, wetter conditions in northern regions.
    • Defined as average weather over a long period (30+ years), while weather refers to current atmospheric conditions.

    Climatic Zones

    • Four main climatic zones: Sub-tropical Continental Highland, Sub-tropical Continental Plateau, Sub-tropical Continental Plain, Tropical Coastal.
    • Geographical location and altitude influence the diverse climate.

    Lowland Climate

    • Found in Punjab and Sindh; summers are arid with mild winters.
    • Monsoon season from June to September, with varying rainfall depending on proximity to mountains.
    • Pothwar Plateau receives more rain due to both monsoon and western depressions influence.

    Desert or Arid Climate

    • Includes regions like Kharan, Cholistan, Thal, and Thar.
    • Characterized by dry, hot summers and cold winters with minimal precipitation.
    • High diurnal temperature range and frequent dust storms.

    Coastal Climate

    • Coastal region stretches from Rann of Kutch to the Makran coast.
    • Maritime climate with year-round sea breezes and high humidity (April to September).
    • Limited rainfall from monsoons and some from western depressions.

    Seasons of Pakistan

    • Four distinct seasons: Spring (March-May), Summer (June-September), Autumn, and Winter.
    • Spring temperatures range from 15°C to 25°C; summer experiences hot, dry conditions.

    Monsoon Systems

    • Bay of Bengal Monsoon brings heavy rains, particularly to northern Punjab due to land-sea heating differences.
    • Arabian Sea Monsoon provides rainfall to coastal areas but can lead to severe flooding and landslides.

    Climate Characteristics of Karachi

    • Hot desert climate with temperature fluctuations from 12.5°C in December to 34.0°C in June.
    • April has lowest average rainfall (0 mm), July sees highest (52 mm).

    Factors Influencing Temperature Variations

    • Key elements: Temperature, Pressure, Winds, Rainfall.
    • Temperature decreases by approximately 6°C for every 1000 ft increase in altitude.
    • Other influencing factors include cloud cover, continental effect, and angle of the sun.

    Highland Climate

    • Characterized by long, cold, snowy winters and mild summers.
    • High rainfall in northern and northwestern mountains with varied conditions in western mountains.

    Rainshadow Areas

    • Areas like Gilgit and Chitral experience reduced rainfall due to their position on the leeward side of mountain ranges.

    Convectional and Relief Rainfall

    • Relief rainfall common in northern and western regions, particularly the Himalayas and Karakoram ranges.
    • Convectional rainfall occurs in early summer in northern Punjab and KPK due to heated land surfaces.

    Western Disturbances

    • Low-pressure systems from the Mediterranean bring winter rainfall and snowfall, crucial for agriculture.
    • Notable influence on northern and western Pakistan from November to April.

    Summary of Temperature Ranges

    • Northern Region: Summer avg 17°C, winter avg -2°C.
    • Central Region: Summer avg 25°C, winter avg 10°C.
    • Southern Region: Hottest, summer avg 28°C, winter avg 18°C.
