Climate, Climatologists, Climatology

  • By Kelly, Mike and Jamie
  • October 20th, 2009

Climate
  • Climate is long term weather patterns for an area
  • Average temperature and precipitation over time
  • Ways to figure out climate amount of sunshine,
    average wind speeds and directions, number of
    days above freezing, weather extremes, and local
    geography

Francis Galton
  • Galton launched his scientific career with an
    expedition to tropical Africa and subsequent
    election to the Royal Geographical Society.
  • By studying inheritance statistically, Galton
    founded the "biometric" approach to genetics.
  • Galton founded Differential Psychology, sometimes
    called the "London School" of experimental
    psychology..
  • The study of heredity could only be placed on a
    scientific basis by introducing new statistical
    concepts like regression and correlation. 
  • Galton first described the anti-cyclone and
    pioneered the introduction of weather-maps based
    on charting data about air pressure.

Edmund Halley
  • English astronomer who established the first
    observatory in the southern hemisphere on the
    island of St. Helena.
  • After studying comets, he noticed that the path
    of the comets of 1456, 1531, and 1607 were
    surprisingly similar.
  • He surmised that these three sightings were
    different apparitions of a single comet, which he
    predicted would return again around 1758.
  • He died before his prediction was tested, but
    the comet indeed returned and has been known as
    Halley's Comet ever since. When Flamsteed died in
    1720, Halley was appointed Royal Astronomer at
    Greenwich Observatory.

Whaldimir Köppen
  • German meteorologist, climatologist and botanist.
  • He elaborated the Köppen climate classification
    system, which is still commonly used today to
    group climates into similar types (albeit with
    modifications).
  • responsible for establishing a weather
    forecasting service for the northwestern part of
    Germany and the adjacent sea areas. After four
    years of service, he was able to move on to his
    primary interest - the fundamental research - and
    left the meteorological office.
  • Köppen began a study of the climate and also
    experimented with balloons to obtain data from
    upper air. This work led to the development of
    the Köppen climate classification system around
    1900.
  • The full version of his system appeared first in
    1918 and, after several modifications, the final
    version was published in 1936. .
  • Alfred Wegener was his son-in-law

6
Milutin Milankovic
  • The Serbian astrophysicist Milutin Milankovitc is
    best known for developing one of the most
    significant theories relating Earth motions and
    long-term climate change 
  • Born in 1879 in the rural village of Dalj
  • Milankovitc dedicated his career to developing a
    mathematical theory of climate based on the
    seasonal and latitudinal variations of solar
    radiation received by the Earth.
  • Milankovitc Theory, it states that as the Earth
    travels through space around the sun, cyclical
    variations in three elements of Earth-sun
    geometry combine to produce variations in the
    amount of solar energy that reaches Earth
  • Variations in the Earth's orbital
    eccentricitythe shape of the orbit around the
    sun.
  • Changes in obliquitychanges in the angle that
    Earth's axis makes with the plane of Earth's
    orbit.
  • Precessionthe change in the direction of the
    Earth's axis of rotation,
  • Orbital motions have become known as Milankovitc
    cycles.

Hubert Lamb
  • English climatologist  
  • Refused to work on the meteorology of gas
    spraying during World War II 
  • Founder and first Director (1971-1977) of the
    Climatic Research Unit.

Köpplens Classification
  • Groups of climates into similar types
  • Five major climate types based on the annual and
    monthly averages of temperature and precipitation

Climate Affect Biomes
http//www.teachersdomain.org/asset/ess05_int_biom
emap/
  • Biome is defined by its climate and the types of
    plants and species of animals that live there.

Tundra Forest Savanna Taiga Rainforests Chapar
ral Grasslands Alpine Desert-scrub Desert
10
Areas most affected by Climate
  • So if a lush tropical rain forest stops getting
    rain. Pretty soon all the plants and animals will
    die out or adapt, or flee from that area. Pretty
    soon that tropical rain forest will turn into a
    desert. A desert biome has some characteristics
    and a tropical rain forest has some others.
  • If the climate changes, the whole biome will be
    affected and will turn into something else.
    sometimes the change is positive and sometimes
    negative. if u switch the rainforest thing
    around, then the affect is positive.
  • Marine biome has the most diversity

11
Climate affect Biodiversity
  • Variation of life forms within a given ecosystem,
    biome, or for the entire Earth.
  • Scientists predict that climate change will
    significantly affect the land base and the living
    organisms and communities that depend on it.
  • Global warming is recognized as a key threat to
    biodiversity.
  • Used as a measure of the health of biological
    systems
  • The biodiversity found on Earth today consists
    of many millions of distinct biological species,
    which is the product of nearly 3.5 billion years
    of evolution.
  • Environmental conditions play a key role in
    defining the function and distribution of plants,
    in combination with other factors.
  • Changes in long term environmental conditions
    that change the climate are known to have had big
    impacts on plant diversity patterns in the past
    and are seen as having significant current
    impacts.
  • Predicted that climate change will remain one of
    the major drivers of biodiversity patterns in the
    future.
  • Marine biome has the most diversity

12
Areas least affected by Climate
  • Biomes are defined as "the world's major
    communities, classified according to the
    predominant vegetation and characterized by
    adaptations of organisms to that particular
    environment"
  • The importance of biomes cannot be
    underestimated. Biomes have changed and moved
    many times during the history of life on Earth.
    More recently, human activities have drastically
    altered these communities. 
  • Desert and Arctic biomes have the least
    precipitation. 
  • San Francisco is one of the most affected areas
    by precipitation.
  • The biome that is least affected by biodiversity
    aerial biome because nothing live in the air
    except for some bacteria and viruses
