UK Physical Geography and Weather

UK Physical Geography

• The UK is mostly lowland, with scattered hilly areas.
• Central England has mountainous regions like the Pennines.
• The UK lies within a temperate climate zone, resulting in warm summers and cool winters.

Factors Affecting UK Weather

• Temperature: Affects weather significantly.
• Air Pressure: Influences weather patterns.
• Cloudiness: Impacts weather conditions.
• Wind: Influences weather conditions.
• Humidity: Plays a role in weather.
• Rain: Precipitation is a key weather element.
• Distance from the Equator: Closer to the equator means warmer temperatures.

Air Masses Affecting the UK

• Air masses are large bodies of air with consistent temperature and humidity.
• Air mass properties depend on the source region.
• 6 air masses influence the UK.

Tropical Maritime

• Originates in the tropical southwest (warm, humid).
• Often damp and mild.
• Travel cools, leads to low clouds, sea fog, and drizzle (especially western UK).

Tropical Continental

• Brings UK's hottest summer weather.
• From Southern Europe and North Africa (hot, dry, and sunny).
• Can cause thunderstorms.

Polar Maritime

• Originates in Greenland or Arctic Canada (cold source).
• Heated by North Atlantic, resulting in instability and potential for hail, thunder, and lightning (mainly northwest UK).

Returning Polar Maritime

• Originates in Greenland or Arctic Canada (cold source).
• Extended time over North Atlantic makes it humid and unstable (cloudiness and heavy showers, west of UK).

Arctic Maritime

• Primarily affects the UK in winter.
• Arrives from the Arctic.
• Warm over some milder seas, creating instability (shower clouds).
• Remains cold due to its sea journey route (can result in snow).

Polar Continental

• Brings the UK's coldest winter weather.
• From Eastern Europe, Scandinavia, or Siberia (cold weather)
• Travels over the North Sea, picks up moisture and becomes unstable (snow and showers, east of UK).

UK Regional Weather Patterns

• Northwest UK: Cold and wet.
• Northeast UK: Cold and dry.
• Southwest UK: Warm and wet.
• Southeast UK: Warm and dry.

Map Skills & Relief

• Contour lines on maps show height above sea level (in meters).
• Relief describes land shape (height and steepness).

Coastal Management

• Coastlines need management to prevent erosion and flooding.
• Hard Engineering: Artificial structures (groynes, sea walls, barriers, gabions, breakwaters).
  • Stops natural processes.
  • Permanent and expensive.
  • Absorbs wave energy.

Hard Engineering Strategies

• Groynes:

  • Barriers to stop longshore drift, leading to sand buildup.
  • Advantages: Attracts tourists, increases biodiversity, relatively cheap.
  • Disadvantages: Restricts swimming, unattractive, poorly maintained.

• Sea Walls:

  • Large concrete walls that reflect wave energy.
  • Advantages: Effective, made of strong material, protects cliffs.
  • Disadvantages: Expensive, damages ecosystems, destroys habitats, unattractive.

• Soft Engineering: Natural, sustainable approach that works with nature.

• No artificial structures.

Economic Sectors

• Primary: Collecting or growing raw materials (farming, fishing, mining).
• Secondary: Manufacturing raw materials into products (factories, machinery).
• Tertiary: Providing services or selling products (teachers, doctors, commerce, transport, banks).
• Quaternary: Intellectual services like research and development (education, computing).

India Locations

• Location of India's Cities: The relative placement of major cities.
• Neighbouring Countries: Countries surrounding India (Pakistan, China, Bangladesh).

India as a Global Power

• Population: India has the largest population (over 1.64 billion).
• Soft Power: Cultural influence (Bollywood, food, yoga, languages, music).
