Temperature
How hot or cold
Depends on latitude, altitude, distance from sea, terrain, soil, ocean current, wind, time of day, vegetation

pressure
Atm pressure is pressure exerted by weight of atmosphere on earth surface – varies with time and place
Occurs due to differential heating – cause movement of wind which serves as means of transporting heat and moisture
Pressure at point is determined by temperature and density
Atmospheric pressure decreases with increase in altitude and also inversely proportional to temperature
Measured by mercury barometer
Standard pressure is 1034gm/sq cm at sea level or 29.92 inches or 76 mm


wind
Weather: Wind
Wind direction affects temperature
Winds from warm areas will increase temperature
