Iriomote is also home to Pinaisara Falls, the largest waterfall in Okinawa Prefecture. [9] Iriomote has a tropical rainforest climate (Köppen climate classification Af). The average yearly temperature is 23.9 °C (75.0 °F), and the average monthly temperature ranges from 18.5 °C (65.3 °F) in January to 28.9 °C (84.0 °F) in July.
Warm surface water is generally saltier than the cooler deep or polar waters. [1] In polar regions, the upper layers of ocean water are cold and fresh. [2] Deep ocean water is cold, salty water found deep below the surface of Earth's oceans. This water has a uniform temperature of around 0-3 °C. [3]
A wet-bulb temperature at 500 hPa in a tropical atmosphere of −13.2 °C (8.2 °F) is required to initiate convection if the water temperature is 26.5 °C (79.7 °F), and this temperature requirement increases or decreases proportionally by 1 °C in the sea surface temperature for each 1 °C change at 500 hpa.
This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
Weather also changes as altitude increases on the larger islands. Temperature decreases gradually with altitude, while precipitation increases due to the condensation of moisture from clouds on the slopes. This pattern of generally wet highlands and drier lowlands affects the plant life on the larger islands.
The current annual GMST is about 15 °C (59 °F), [6] though monthly temperatures can vary almost 2 °C (4 °F) above or below this figure. [7] The global average and combined land and ocean surface temperature show a warming of 1.09 °C (range: 0.95 to 1.20 °C) from 1850–1900 to 2011–2020, based on multiple independently produced datasets.
An especially strong Walker circulation causes La Niña, which is considered to be the cold oceanic and positive atmospheric phase of the broader El Niño–Southern Oscillation (ENSO) weather phenomenon, as well as the opposite of El Niño weather pattern, [19] where sea surface temperature across the eastern equatorial part of the central ...
August 11, 1945 - Demoted to the Okinawa Weather Station (沖縄測候所, Okinawa Sokkōjo) November 13, 1946 - Okinawa Weather Station was abolished. January 1950 - The Ryukyu Meteorological Administration ( 琉球気象局 , Ryūkyū Kishōkyoku ) was established.
