Understanding Air Pressure and Weather Patterns

🌍 Air influences our lives in many ways and causes meteorological phenomena.

🌡️ Air varies in temperature and humidity, and different air masses have different characteristics.

🌨️⛈️💨 Weather patterns such as snow, rain, and wind are created by air pressure.

❄️ The Siberian Express brings cold and dry weather to Korea in the winter.

☀️🌧️ The Northern Pacific High causes hot and humid conditions, leading to the rainy season and hot summers in Korea.

🌬️🏔️ The Foehn Effect, caused by the Okhotsk High, creates a dry and warm wind that affects local winds in Korea.

⚡️ Weather changes occur when a front passes through an area.

🌦️ Cold fronts cause air temperatures to drop, while warm fronts cause temperatures to rise.

☁️ Different types of clouds form depending on the front, such as cumulus clouds behind cold fronts and stratus clouds behind warm fronts.

💨 Air moves from high pressure to low pressure, creating wind.

☁️ Low pressure areas result in cloudy, rainy, or snowy weather, while high pressure areas have clear weather.

🔄 High pressure zones can be stationary or migratory, while low pressure zones can be temperate or tropical.

🌧️ Stratus clouds and light rain form ahead of temperate fronts in low pressure zones.

☀️ Clear weather and hot air temperatures occur between a cold front and a warm front.

⛈️ Cumulus clouds and showers form behind a cold front in low pressure zones.

🌪️ Typhoons originate over tropical seas and move north, changing direction at the typhoon's turning point.

🌊 When a typhoon weakens, the pressure at its center rises, causing it to die out, and intense typhoons cause sea levels to rise.

💧 The sea level rises due to the low air pressure and winds of the typhoon, and typhoon surges cause more damage when they occur at high tide.

💨 Air has a significant impact on both our daily weather and natural disasters.

🌍 Atmospheric circulation occurs on a global scale and will be discussed in the next lecture.
