Short-term changes in climate are common. The largest and most important of these is the oscillation between El Niño and La Niña conditions. … In an El Niño year, when water temperature reaches around 28 degrees C (82 degrees F), the trade winds weaken or reverse direction and blow east (toward South America).
What is a short term climate variation?
As we have seen, climate variability describes short-term changes in climate that take place over months, seasons and years. This variability is the result of natural, large-scale features of the climate that we looked at earlier.
What are the short and long term consequences of climate change?
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.
What are short term atmospheric changes?
Answer: Short term changes in atmosphere is known as the “Weather”. Explanation: Weather is the environment of the atmosphere, which describes the standard to which it is wet or dry, cold or hot, stormy or calm, sunny or cloudy.
What causes climate variability?
Climate variability is the way aspects of climate (such as temperature and precipitation) differ from an average. Climate variability occurs due to natural and sometimes periodic changes in the circulation of the air and ocean, volcanic eruptions, and other factors.
What are natural causes of climate change?
The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean currents, the Earth’s orbital changes, solar variations and internal variability.
What are 5 effects of climate change?
What are the effects of climate change?
- rising maximum temperatures.
- rising minimum temperatures.
- rising sea levels.
- higher ocean temperatures.
- an increase in heavy precipitation (heavy rain and hail)
- shrinking glaciers.
- thawing permafrost.
What are the 5 causes of climate change?
5 Causes of Global Warming

- Cause #1: Variations in the Sun’s Intensity. …
- Cause #2: Industrial Activity. …
- Cause #3: Agricultural Activity. …
- Cause #4: Deforestation. …
- Cause #5: Earth’s Own Feedback Loop.
What affects the climate of an area?
Introduction: Climate is determined by the temperature and precipitation characteristics of a region over time. The temperature characteristics of a region are influenced by natural factors such as latitude, elevation, and the presence of ocean currents. … These too, are natural factors that influence precipitation.
Is climate short term or long-term?
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
How do wind currents affect short term climate in a region?
How do changes in wind currents affect the short-term climate in a region? … They change the amount of precipitation in an area and affect a region’s climate.
Are seasons short term or long-term?
Seasonal changes and changes that result from the interaction between the ocean and the atmosphere are some examples of short term climate changes. Changes in the amount of dollar energy received at different latitudes during different times of the year, give rise to the seasons.
What are the 6 major factors that affect climate?
LOWERN is an acronym for 6 factors that affect climate.
- Latitude. It depends on how close or how far it is to the equator. …
- Ocean currents. Certain ocean currents have different temperatures. …
- Wind and air masses. Heated ground causes air to rise which results in lower air pressure. …
- Elevation. …
- Relief.
What is cause and effect of climate change?
Human activities, such as burning fossil fuels and destroying rainforests, have an increasing influence on the climate and the Earth’s temperature. This adds huge quantities of greenhouse gases to those naturally present in the atmosphere, increasing the greenhouse effect and global warming.
What causes climate change for kids?
The primary cause of climate change is human activities – like driving cars, creating electricity, and cutting down forests – not natural changes in the climate. These human activities release gases into the atmosphere called greenhouse gases, which slowly warm the planet, creating climate change.
