Weather
Convectional Typical of hot climates, convection occurs after morningsunshine heats warm moist air. Clouds form in the afternoon and rain falls.
Frontal Mid-latitude frontal storms feature cold dense air masses that push lighter warm air masses upward,Causing precipitation to form.
Orographic Associated with mountain areas, orographic storms drop more rain on the windward side of a mountain and create a rain shadow on the leeward side.

The Siberian Taiga is the largest forest on earth, and makes up 27% of the World's total forested land. Many species found here are also found in Ireland, especially the two most common species, silver birch and Scots pine.
The Altai Mountains lie on the borders of Siberia, Tibet and Mongolia. The people living in this region subsist almost entirely from their sheep for their food, clothing and even alcohol! Low rainfall and bitterly cold winters make this a harsh environment for people and wildlife.
