It can be caused by not receiving rain or snow over a period of time. We learned in the discussions about the water cycle and weather that changes in the wind patterns that move clouds and moisture through the atmosphere can cause a place to not receive its normal amount of rain or snow over a long period of time.

Answer:
Earth's climate and weather systems are continually evolving. Extremes of temperature, precipitation, and air motion will naturally happen as part of these dynamic procedures. Therefore, periods of extraordinary dryness, droughts, are standard characteristics of climate and weather systems in all nations, including those generally considered to be "moist" and "cold," as well as those regions usually connected with the word "drought"- the semi-arid tropical regions. While droughts may be considered unusual in that they do not happen all the time or most of the moment in some regions, droughts should not be considered "abnormal" and should in reality be scheduled in all nations. Researchers have discovered that air pollution is significantly reducing rainfall in Chinese hills. In many other extremely polluted areas, which rely on neighbouring mountains for their water, the same impact is likely to cause water shortages. Meteorologists have long believed that this precipitation can be suppressed or delayed by pollution. Small particles known as "aerosols" are known to change the size and characteristics of cloud-forming water droplets and can influence the weather in several ways.
