Is the vehicle temperature gauge inaccurate?

<p style=";text-align:left;direction:ltr">Weather of Arabia - Director of the Meteorological Department, Raed Rafid Al Khattab, said that there are frequent questions about temperatures, especially their forecasts, and controversy usually arises over the difference between the temperatures recorded by weather monitoring stations and those shown by thermometers in vehicles, which cannot be Consider it accurate.</p><p style=";text-align:left;direction:ltr"> Al Khattab explained that the measurement of various weather elements is done according to specific scientific standards approved by the World Meteorological Organization (WMO), and these standards are applied in all weather monitoring stations around the world to ensure the accuracy of the readings. He pointed out that measuring temperatures requires protecting the measuring devices from sunlight. Direct or influence of surrounding objects, so manual or automatic measuring devices are placed inside a wooden box painted white, containing openings on all sides that allow air to enter and exit, while preventing the entry of sunlight. This box is installed facing north and at a height of two meters above the ground to avoid the effect of thermal radiation bouncing off the ground. </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="/sites/default/files/uploads-2020/%D9%87%D9%84%20%D9%85%D9%82%D9%8A%D8%A7%D8%B3%20%D8%AF%D8%B1%D8%AC%D8%A7%D8%AA%20%D8%A7%D9%84%D8%AD%D8%B1%D8%A7%D8%B1%D8%A9%20%D8%A8%D8%A7%D9%84%D9%85%D8%B1%D9%83%D8%A8%D8%A7%D8%AA%20%D8%BA%D9%8A%D8%B1%20%D8%AF%D9%82%D9%8A%D9%82%D8%9F.jpg" style="width: 800px; height: 532px;" /></p><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"> Is the vehicle temperature gauge inaccurate?</h2><p style=";text-align:left;direction:ltr"> As for temperature gauges in vehicles, Al Khattab pointed out that they are useful for giving a general idea of the temperature of the atmosphere outside the vehicle, but they are not accurate because they are affected by multiple factors such as the location and movement of the vehicle, direct solar radiation, the color of the car, the reflection of the heat of the asphalt, and the temperature of the exhausts issued by the surrounding vehicles. These factors make it not meet the globally uniform measurement conditions and standards, which leads to differences when compared with the readings of approved monitoring stations.</p><p style=";text-align:left;direction:ltr"> Al Khattab stressed that the temperatures issued by meteorology, whether in summer or winter, are accurate and rely on the principle of transparency and credibility, far from exaggeration or exaggeration. All readings are documented locally in the climate record, and are sent daily to meteorological centers accredited by the World Meteorological Organization. To ensure the continuous availability of information.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> See also:</p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D9%86%D8%B5%D8%A7%D8%A6%D8%AD-... and nutritional tips for Eid al-Adha</a></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/4-%D9%85%D8%B4%D8%B1%D9%88%D8%A... healthy drinks to treat dehydration in the summer</a></p><p style=";text-align:left;direction:ltr"></p><hr /><p style=";text-align:left;direction:ltr"> Sources:</p><p style=";text-align:left;direction:ltr"> <a href="https://www.khaberni.com/news/%D8%A7%D9%84%D8%A3%D8%B1%D8%B5%D8%A7%D8%AF...
