The precipitable water can also be calculated by integration of radiosonde data (relative humidity, pressure and temperature) over the whole atmosphere. Data can be viewed on a Lifted-K index. The numbers represent inches of water as mentioned above for a geographical location. Recently, methods using the Global Positioning System have been ...
It is defined as the pressure exerted by a column of water of 1 inch in height at defined conditions. At a temperature of 4 °C (39.2 °F) pure water has its highest density (1000 kg/m 3). At that temperature and assuming the standard acceleration of gravity, 1 inAq is approximately 249.082 pascals (0.0361263 psi). [2]
The blue numbers are the amount of precipitation in either millimeters (liters per square meter) or inches. The red numbers are the average daily high and low temperatures for each month, and the red bars represent the average daily temperature span for each month. The thin gray line is 0 °C or 32 °F, the point of freezing, for orientation.
To accommodate the lowest points on Earth, the model starts at a base geopotential altitude of 610 meters (2,000 ft) below sea level, with standard temperature set at 19 °C. With a temperature lapse rate of −6.5 °C (-11.7 °F) per km (roughly −2 °C (-3.6 °F) per 1,000 ft), the table interpolates to the standard mean sea level values of ...
The concept of potential temperature applies to any stratified fluid. It is most frequently used in the atmospheric sciences and oceanography. [2] The reason that it is used in both fields is that changes in pressure can result in warmer fluid residing under colder fluid – examples being dropping air temperature with altitude and increasing water temperature with depth in very deep ocean ...
At the South Pole, the highest temperature ever recorded was −12.3 °C (9.9 °F) on 25 December 2011. [16] Along the Antarctic Peninsula, temperatures as high as 18.3 °C (64.9 °F) have been recorded, [clarification needed] though the summer temperature is below 0 °C (32 °F) most of the time. Severe low temperatures vary with latitude ...
Average yearly temperature is 22.4 °C, ranging from an average minimum of 12.2 °C to a maximum of 29.9 °C. The average temperature range is 11.4 °C. [6] Variability throughout the year is small (standard deviation of 2.31 °C for the maximum monthly average and 4.11 °C for the minimum). The graph also shows the typical phenomenon of ...
Winter temperatures are much less uniform. Coastal areas of the state have very mild winters with high temperatures averaging about 60 °F (16 °C) and overnight lows close to 38 °F (3 °C). Further inland in the Piedmont, temperatures average between 50 °F (10 °C) during the day and 32 °F (0 °C) at night.
