Meteorology: World Climate and Climate Change

Meteorology

The study of the atmosphere and the processes that cause weather.

Weather

Short-term atmospheric conditions (hours to days).

Climate

Average atmospheric conditions over a long period (usually 30+ years).

Solar Radiation

The primary energy source for Earth's climate, varying by latitude.

Atmospheric Circulation

Large-scale movement of air that distributes thermal energy globally.

Ocean Currents

Currents that absorb and redistribute heat, affecting coastal temperatures.

Topography

The natural and artificial physical features of an area, influencing local climates.

Proximity to Water

Areas near large bodies of water have milder climates due to water's heat retention.

Albedo Effect

The reflectivity of Earth's surface, affecting climate through energy reflection.

Volcanic Activity

Eruptions that release dust and gases, temporarily cooling the Earth.

Climate Change

Significant, long-term changes in temperature, precipitation, and climate patterns.

Greenhouse Effect

Gases that trap heat in the atmosphere, warming the planet.

Human-Induced Climate Change

Climate change caused by human activities like burning fossil fuels and deforestation.

Positive Feedback

Mechanisms that amplify changes in climate (e.g., ice melt reducing albedo).

Negative Feedback

Mechanisms that reduce the impact of climate changes (e.g., increased cloud cover).

Köppen Climate Classification

A system that categorizes the world’s climates based on temperature and precipitation.

Global Wind Patterns

Winds driven by Earth's rotation and heat distribution, influencing climate.

Jet Streams

Fast flowing, narrow air currents that affect weather systems and climate.

El Niño

Periodic warming of the Pacific Ocean that alters global weather patterns.

La Niña

Cooling of the Pacific Ocean, often producing opposite effects to El Niño.

Monsoons

Seasonal wind patterns causing heavy rains in certain regions.

Climatological Data

Data used to analyze and interpret climate and climate change.

Temperature Graphs

Visual representations tracking changes in average global temperatures over time.

Precipitation Charts

Graphs showing rainfall trends in different regions.

CO₂ Concentration Graphs

Graphs tracking atmospheric CO₂ levels over time.

Climate Maps

Maps showing different climate zones and global patterns.

Anomaly Maps

Maps indicating deviations from long-term averages in temperature or precipitation.

Satellite Images

Visual data tracking changes in sea ice, deforestation, and atmospheric conditions.

Ice Core Data

Historical records of atmospheric composition and past climate conditions from glaciers.

Rising Temperatures

Global warming leading to more frequent heatwaves and changing weather patterns.

Melting Polar Ice

Loss of ice contributing to rising sea levels and coastal flooding.

Ocean Acidification

Increased CO₂ absorption by oceans leading to harmful acidic waters for marine life.

Extreme Weather Events

More frequent and intense storms, droughts, and floods due to climate change.

Ecosystem Impact

Changes in climate forcing species to adapt, migrate, or face extinction.

Mitigation

Efforts to reduce or prevent greenhouse gas emissions.

Adaptation

Adjusting to the effects of climate change through various strategies.

Data Analysis

Identifying trends and anomalies in climate data.

Hypothesis Formation

Developing hypotheses about climate patterns and changes based on data.

Quantitative Analysis

Using numerical data to understand climate phenomena.

Qualitative Analysis

Using descriptive information to understand climate phenomena.

Climate system

The atmosphere, hydrosphere, lithosphere, and biosphere
