What are the causes of rainfall in Zambia?

Although Zambia lies within the tropics, its climate is modified by the altitude of the country and is generally favourable to human settlement and comfort. The marked seasonal pattern of precipitation is caused by the north and south movement of the intertropical convergence zone (ITCZ), which shifts with the Sun.

In which season does relief rainfall occur in Zambia?

Zambia normally receives the bulk of its annual rainfall from November through out March as the ITCZ moves south.

What causes increased rainfall?

Human-caused climate change intensifies the heaviest downpours. More than 70% of the planet’s surface is water, and as the world warms, more water evaporates from oceans, lakes, and soils. Every 1°F rise also allows the atmosphere to hold 4% more water vapor.

Which part of Zambia has relief rainfall?

The highest rainfall is in the north, especially the north-west and the north-east, decreasing towards the south; the driest areas are in the far south west and the Luangwa River and middle Zambezi River valleys, parts of which are considered semi-arid.

What is the causes of rainfall?

What causes rain? Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.

Why is rainfall decreasing?

The proximate or immediate cause of a rainfall shortage may be due to one or more factors including an absence of available moisture in the atmosphere; large scale subsidence (downward movement of air within the atmosphere) which suppresses convective activity; and the absence or non-arrival of rain-bearing systems.

How is rainfall affected by climate change?

Climate change can affect the intensity and frequency of precipitation. Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rain and snow storms.
