The statements, "Its rainy today." and "It's always rainy in July." emanate from two different concepts. The first refers to the current atmospheric conditions on a particular day. The second indicates an expectation of the weather conditions based on a norm. It is often said that climate is what you expect and weather is what you get! A more geographic explanation is weather is the current condition of the atmosphere over a few days to a few months. This includes factors such as rainfall and temperature. Climate is the average weather conditions of a place over a period of at least 30 years.

  Elements of weather: Wind  is air in motion. Air molecules tend to move from areas of high pressure to low pressure. Theoretically, cold dense air from the Polar regions should blow towards the equator and fill the void where heat warms up the air and causes air molecules to rise and spread out . However, the spinning of the Earth exerts a force on these currents of air, making them deflect to the left in the Northern Hemisphere and to the right in the Southern Hemisphere. This is called the Coriolis Effect. Other local factors affect wind speed and direction such as the uneven heating of the Earth's surface, and the presence of mountains. Winds transport heat and coldness, moisture and dust for great distances and is has a significant influence on weather conditions. Wind speed is measured by an  anemometer  while wind direction is measured by a  wind vane or wind sock . The Coriolis effect
