Study Notes
Physical Factors in the Atmosphere: Heat
- The Sun is Earth's primary heat source
- Sunlight warms land and water, then transfers heat to the atmosphere
- Different Earth parts receive varying sunlight amounts, leading to temperature differences
- These differences drive weather patterns (wind, rain, storms)
Measuring Air Temperature
- Meteorologists measure air temperature to understand weather patterns, comparing current data to past records
- Temperature is measured using different scales:
- Fahrenheit (°F) - used in the US
- Celsius (°C) - used in many countries, including Egypt
- Kelvin (K) - used in scientific calculations
- Conversion formulas:
- Celsius to Fahrenheit: F = (9/5)°C + 32
- Fahrenheit to Celsius: C = (F - 32) x 5/9
- Celsius to Kelvin: K = C + 273
- Kelvin to Celsius: C = K - 273
Mechanisms of Heat Transfer
- Conduction: Heat transfer through direct contact (solid objects) from higher to lower temperature areas
- Convection: Heat transfer within fluids (liquids & gases). Warmer, less dense fluids rise, cooler, denser fluid sinks, creating currents
- Radiation: Heat transfer through electromagnetic waves, doesn't require a medium (e.g., heat from the sun).
Atmospheric Pressure:
-
Air moves from areas of high pressure to low pressure, creating wind
-
Low-pressure systems: Associated with rising warm air, clouds, precipitation, and stormy weather
-
High-pressure systems: Associated with sinking cool air, clear skies, and stable weather
-
High-Altitude Effects: Lower pressure at higher altitudes leads to reduced oxygen availability, causing altitude sickness (headache, nausea, shortness of breath).
-
The body compensates by producing more red blood cells, to carry more oxygen
-
Blood Pressure & Humidity: Changes in both can impact blood pressure, particularly in people with specific conditions
-
Coriolis Effect: The Earth's rotation affects wind patterns.
Humidity
- Humidity: The amount of water vapor in the air
- High humidity: Associated with more clouds and rain, especially in tropical regions. Warmer air can hold more water vapor.
- Saturated air: Air that can't hold any more water vapor
- Hygrometer: Instrument used to measure humidity
- High humidity: Reduced sweat evaporation, increased perceived temperature
- Low humidity: Dry skin, increased susceptibility to skin infections
- Effect on Plants and Animals: Humidity impacts plant transpiration and animal cooling mechanisms.
Adaptation to Extreme Conditions
- Organisms adapt to climate factors (temperature, pressure) over time, demonstrating remarkable abilities to survive in extreme environments
- Example: Wood Frogs – partially freeze in winter, glucose prevents ice crystal formation, and resume normal functions in spring
- Example: Antarctic Icefish – antifreeze proteins in blood, no hemoglobin; use cold water to absorb oxygen
- Example: Desert Lizards – behavioral (seeking shade) and physiological adaptations (efficient water retention) for high temperatures.
