In fig 15.4(a) the climograph indicates for most of the year temperature remains below zero, seldom rises above 0 degree celsius and precipitation is nil in winter months however very low precipitation occurs during summer months ranging about 1mm - 5mm (0.1 cm - 0.5 cm).
According to Koppen climatic classification the name of the climate is Polar climate.
Koppen symbol is ET.
In fig 15.4(b) the climograph indicates temperature remains relatively low reaching a maximum of about 20 degree celsius temperature, in summer months railfall is very low, i.e., dry summers and precipitation is maximum during winters.
According to Koppen classification the name of the climate is Cool Dry-Summer.
Koppen symbol is Csb.
In fig 15.4(c) the climograph indicates temperature reaches an anuual maximum of about 20 degree and maximum annual low of about -15 degrre celsius. Precipitation is maximum during summers and low during winters however precipitation occurs throughout the year.
According to Koppen Classification the climate name is Warm Humid-Continental.
Koppen symbol is Dfb.
In fig 15.4(d) the climograph indicates temperature reaches an annual maximum of 15-20 degree celcius and maximum annual low of about 10-8 degree celisus. Precipitation is nil during summers and reaches to a high of about 10 cm during winters. Warm and temperate conditions prevails.
According to koppen classification the name of the climate will be Dry-Summer Mediterranean/ Cool Summer Mediterranean.
Koppen symbol is Cs.
In fig15.4(e) the climograph indicates a maximum annual temperature of about 30 degree celsius and maximum annual low of about 10-8 degree celsius. Precipitation occurs throughout the year and being highest during summers and average precipitation during winters. Thus, a humid climate prevails throughout the year.
According to Koppen classification the name of the climate is Humid Sub-tropical.
Koppen symbol is Cfa.
e) It will be dry at 71 degree latitude in Barrow, Alaska. Since the climograph of Barrow, Alaska shows a typical dry pattern with very scanty amount of rainfall that also during the summers, whereas winters remain rain-free.
