Effects of Climate and Morphology on Temperature Conditions of Lakes

This book describes studies about how climate
affects thermal development in lakes. Numerical
models based on physics and mathematical methods
were applied to lakes with different sizes, shapes
and locations. Also diurnal changes and the shape of
the vertical temperature profile were studied. The
depth of the lake affects together with other
morphological features (e.g. the shape and the size)
the one-dimensional basic connection between air and
water, more in smaller lakes. Also the surrounding
landscape affects the conditions over the lake. A
special study area was southern Finland, where
numerous lakes are found. Data over about 100 past
years were used for lakes in the area with the
radius of about 100 km. Future changes were analyzed
with climate change scenarios. Models and data were
compared globally. Thermal conditions in lakes are
important for many areas. They influences how lakes
develop, because physical conditions, e.g. existence
of ice cover, create basic settings for several
processes in lakes. They have been used to
distinguish between lakes in different areas, as
basis for observation systems and even for climate
indicators, like ice cover.
