  7. In tropical areas, monsoons are critical for agriculture.
  8. Monsoon rainfalls contribute to the majority of annual precipitation in some regions.
  9. The monsoon winds originate from the oceans, bringing moisture-laden air.
  10. The monsoon’s arrival is often linked to a decrease in air pressure over the land.
  11. The strength and onset of the monsoon can vary due to ocean temperatures.
  12. A delay in the monsoon’s arrival can lead to drought conditions.

Atmospheric Pressure:

  1. Atmospheric pressure is the weight of air over a given area.
  2. It is measured in millibars (mb), equal to 100 N/m² or 1000 dynes/cm².
  3. Pressure decreases with altitude.
  4. Hot air causes low pressure, and cold air leads to high pressure.
  5. Atmospheric pressure varies due to temperature, altitude, moisture, and the Earth’s rotation.
  6. Unequal heating of the Earth causes pressure differences.
  7. Diurnal variations in pressure occur due to the heating and cooling of the Earth’s surface.
  8. Pressure is lower at the equator and higher at the poles.
  9. High pressure zones typically form over continents in cold seasons.
  10. Low pressure areas form over oceans during warm seasons.
  11. The Equatorial Trough is a low pressure zone near the equator.
  12. Subtropical high-pressure belts exist between 25° and 35° latitude.
  13. Subpolar low-pressure belts are found at 60° to 70° latitudes.
  14. Polar highs exist at the poles, creating cold, dense air.
  15. The Coriolis force, due to the Earth’s rotation, influences wind and pressure systems.
  16. Low-pressure systems are also called cyclones or depressions.
  17. High-pressure systems are called anticyclones.
  18. Cyclones rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Wind Systems:

  1. Wind is air in horizontal motion.
  2. Wind is caused by pressure differences on Earth’s surface.
  3. Winds are named based on the direction they come from.
  4. Doldrums occur at the equator, characterized by light, variable winds.
  5. Trade winds blow from the northeast in the Northern Hemisphere and southeast in the Southern Hemisphere.
  6. Prevailing westerlies occur between 30° and 60° latitude in both hemispheres.
  7. Polar easterlies are cold winds flowing from the poles to 60° latitude.
  8. Winds are deflected by the Coriolis effect, creating distinct wind patterns.
  9. Mountain winds flow uphill during the day and downhill at night.
  10. Valley winds blow from the valley base uphill during the day.
  11. Sea breezes occur when air flows from the cooler sea to the warmer land during the day.
  12. Land breezes occur when cool air flows from land to sea at night.
  13. The sea breeze is stronger during summer days, and land breezes are stronger at night.
  14. Local winds can influence local weather patterns.
  15. Wind helps in the dispersal of seeds and pollination in plants.
  16. Wind can cause mechanical damage to crops.
  17. Winds contribute to soil erosion.
  18. Wind direction is measured using a wind vane.
  19. The strength of wind is measured using an anemometer.
  20. Winds can influence humidity levels and the distribution of moisture.

Low and High-Pressure Systems:

  1. A depression is a low-pressure system with winds moving towards the center.
  2. Anticyclones are high-pressure systems with winds moving outward.
  3. A storm is a low-pressure system with wind speeds between 40 to 120 km/h.
  4. Cyclones are tropical storms with wind speeds greater than 120 km/h.
  5. A hurricane is a type of tropical cyclone in the North Atlantic.
  6. Typhoons are tropical cyclones in the western North Pacific.
  7. Tropical storms form over warm ocean waters.
  8. The Coriolis effect influences the rotation of cyclones.
  9. Cyclones cause heavy rain and severe weather changes.
  10. Hurricanes are fueled by the energy from warm ocean water.
  11. Tornadoes are rapidly rotating columns of air.
  12. Tornadoes form from severe thunderstorms, typically in the spring and summer.
  13. Waterspouts are tornado-like phenomena over water.
  14. Thunderstorms are short, intense storms accompanied by lightning.
  15. Thunderstorms develop from cumulonimbus clouds.
  16. Tornadoes are smaller in size compared to cyclones but are highly destructive.

Seasonal Variations:

  1. Seasonal changes in temperature lead to pressure differences between land and ocean.
  2. Diurnal pressure variation is more prominent at the equator.
  3. Seasonal pressure variation is influenced by changes in insolation.
  4. During the summer, low-pressure systems develop over land, while high-pressure systems form over oceans.
  5. In winter, high-pressure systems dominate over land, and low pressure forms over oceans.
  6. The distribution of pressure influences wind direction and weather patterns.
  7. Atmospheric pressure is highest at sea level and decreases with altitude.

Other Atmospheric Phenomena:

  1. Monsoon winds are influenced by both pressure systems and Earth’s rotation.
  2. The strength of monsoon winds can vary based on ocean temperatures.
  3. During the southwest monsoon, winds blow from the southwest to the northeast.
  4. During the northeast monsoon, winds blow from the northeast to the southwest.
  5. Winter rains occur in northern India due to western disturbances.
  6. Summer rainfall is mainly localized and irregular, occurring from March to May.
  7. Sea surface temperatures significantly impact monsoon behavior.
  8. A delay in the monsoon can lead to droughts in agricultural regions.
  9. The monsoon is vital for water resources in many countries, especially in South Asia.
  10. The distribution of pressure affects the strength and direction of wind systems.
  11. Wind patterns and pressure systems are influenced by the Earth’s rotation and temperature.

Wind and Crop Growth:

  1. Winds transport moisture and heat, impacting plant growth.
  2. Wind helps regulate temperature in the atmosphere.
  3. Wind speed influences evaporation rates and water loss from plants.
  4. High winds can cause physical damage to crops and plants.
  5. Winds can aid in the pollination process, supporting crop yields.
  6. Light winds can help in cleaning agricultural products.
  7. Excessively strong or dry winds can damage crops by increasing transpiration.
