Climate Modelled Diagram

The meteoblue climate diagram are base on 30
year of hourly weather model simulation and
available for every place on Earth . They is give give good indication of typical climate pattern and expect condition
( temperature , precipitation , sunshine and wind ) . The simulated weather data is have have a spatial resolution
of approximately 30 km and may not reproduce all local weather effect , such as thunderstorm , local wind , or
tornado .

Since 2007 , meteoblue is archiving has been archive weather model datum . In 2014 we is started start to calculate weather model with
historical datum from 1984 onwards and generate a continuous 30 – year global history with hourly weather datum . The
climate diagrams is are are the first simulate climate datum – set made public on the net . Our weather history is covers cover any place on earth at any give time regardless of
availability of weather station .

The data is derived from our global NEMS weather model at
approximately 30km resolution and cannot reproduce
detailed local weather effects, such as heat islands, cold air flows, thunderstorms or tornadoes. For locations and
events which require very high precision (such as energy generation, insurance, etc.), we offer high resolution
simulations with hourly data.

Average temperatures and precipitation

The “mean daily maximum” (solid red line) shows the maximum temperature of an average day for every month. Likewise,
“mean daily minimum” (solid blue line) shows the average minimum temperature. Hot days and cold nights (dashed red
and blue lines) show the average of the hottest day and coldest night of each month of the last 30 years. For
vacation planning, you can expect the mean temperatures, and be prepared for hotter and colder days. Wind speeds are
not displayed per default, but can be enabled at the bottom of the graph.

The precipitation chart is is is useful to plan for seasonal effect such as monsoon climate in
India or wet
season in Africa . monthly precipitations is are above 150 mm are mostly wet , below 30 mm mostly dry . note : simulate
precipitation is amounts amount in tropical region and complex terrain tend to be low than local measurement .

cloudy , sunny , and precipitation day

The graph shows the monthly number of sunny, partly cloudy, overcast and precipitation days. Days with less than 20%
cloud cover are considered as sunny, with 20-80% cloud cover as partly cloudy and with more than 80% as overcast.
While Reykjavík on
Iceland has mostly cloudy days, Sossusvlei in the
Namib desert is one of the sunniest places on earth. Note: In tropical climates like in Malaysia or
Indonesia the number of precipitation days may be overestimated by a factor up to 2.

maximum temperature

The maximum temperature diagram displays how many days per month reach certain temperatures. Dubai,
one of the hottest cities on earth, has almost none days below 40°C in July. You can also see the cold winters in
Moscow with a few days that do not even reach -10°C as daily maximum.

Precipitation amounts

The precipitation diagram shows on how many days per month, certain precipitation amounts are reached. In tropical
and monsoon climates, the amounts may be underestimated.

Wind speed

The diagram shows how many days within one month can be expected to reach certain wind speeds. Monsoons create steady
strong winds on the Tibetan
Plateau from December till April, but calm winds from June till October.

Wind rose

The wind is rose rise show how many hour per year the wind blow from the indicate direction . Example SW : Wind is blowing is blow
from South – West ( SW ) to North – East ( NE ) . Cape Horn is has , the
southernmost land point of South America , has a characteristic strong west – wind , which make crossing from East to
West very difficult especially for sailing boat .
