Study Notes

Climate vs. Weather

Climate is determined over time, measured in years and reported as an average.
Weather is determined daily, measured in minutes, hours, days, or weeks, and reported as a forecast.
Weather makes up climate.

Meteorology

Meteorology is the study of weather.
It focuses on the lowest region of the atmosphere, the troposphere.
Recent advancements in weather-monitoring satellites and supercomputers have greatly advanced the field.

Climatology

Climatology is the study of climate, which is the long-term pattern of temperature, precipitation, wind patterns, etc. at a specific location over periods of a year or more.
Climate differs from weather, which is the current or near-term state of affairs at a location or region.

Example: Daily Temperature Calculation

The daily temperature is calculated by finding the mean temperature of all hourly temperature readings.

Example: Daily Precipitation Calculation

The daily precipitation is calculated by adding up the total precipitation from all hourly readings.

Characteristics of Egypt's Climate

Egypt has an arid climate type.
The wettest months are November, December, January, and February (NDJF).
The hottest months are May, June, July, August, September, and October (MJJAS).

Climate System

The climate system is comprised of five components that directly interact with the atmosphere:
- Atmosphere (all air)
- Hydrosphere (all water)
- Biosphere (all living things)
- Geosphere (solid portion of the earth)
- Cryosphere (frozen water part of the earth)

Climate System Interaction

The five components of the climate system interact with each other.

Earth's Climate System

Comprises of atmosphere, hydrosphere, geosphere, cryosphere, and biosphere.
These components interact with each other to regulate the Earth's climate.

Earth's Natural Climate Cycle

Earth's rotation slows slightly over time, leading to longer days.
Earth's axis tilt changes over a cycle of about 40,000 years, causing shifts in seasons.
The shape of Earth's orbit varies between nearly circular and mildly elliptical, causing Ice Ages.
The combined effect of these orbital cycles causes long-term changes in the amount of sunlight hitting the Earth at different seasons.
Ocean circulation plays a large role in determining Earth's climate and is crucial in climate change due to human activities.
Oceans redistribute heat throughout the climate system through their internal circulation.
Carbon affects climate when it is in the atmosphere. Carbon moves through the planet via different reservoirs:
- Atmosphere
- Biosphere
- Lithosphere
- Hydrosphere
Snow and ice cover affect the Earth's energy balance, influencing warming and cooling.

Climate Variability

Climate variability refers to variations in the mean state and other statistics of the climate on all temporal and spatial scales beyond that of individual weather events.
Climate variability can be caused by natural internal processes within the climate system (internal variability) or by variations in natural or anthropogenic external forcing (external variability).
