It is also positioned on the western seaboard of Eurasia, the world's largest land mass. These boundary conditions allow convergence between moist maritime air and dry continental air. In this area, the large temperature variation creates instability and this is a major factor that influences the often unsettled weather the country experiences, where many types of weather can be experienced in a single day. Sometimes, shit happens.
