Corona weather clouds1/6/2024 Without knowing how a cloud evolves after seeding, scientists were unsure whether the silver iodide was doing anything at all. One reason: Instruments of decades past couldn't measure water droplet size in clouds in real time. The technique has been used by militaries and civilian governments on and off ever since.īut despite decades of cloud seeding operations, proof that the technique works outside miniaturized clouds created in the lab has been elusive. (He is the brother of writer Kurt Vonnegut, whose fictional ice-nine was partially inspired by the discovery.) Particles like silver iodide can provide a scaffold on which water molecules can align themselves into a crystalline structure or, in other words, freeze. In the 1940s, atmospheric scientist Bernard Vonnegut found that particles of silver iodide can cause supercool clouds of water vapor to freeze into snow in the lab. "What they've done is identify the chain of events from seeding to precipitation on the ground, which has been sorely needed for the last 80 years," says William Cotton, a former professor of atmospheric science at Colorado State University in Fort Collins who was not involved with the research. Now, researchers flying two small planes through a bank of clouds in Idaho have shown, for the first time outside the lab, that humans can artificially turbocharge snowfall. That's because even though scientists have been seeding clouds since the 1940s, there was precious little proof the technique worked. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.Cloud seeding-sowing clouds with small particles to make them rain or snow-has a reputation as dodgy as the weather. The Sun's most intense and consequently most harmful UV radiation during midday hours should be decreased by minimizing exposure and seeking shade. Take precautions - Protection against sun damage is advised. Note: In December, the average maximum UV index of 4 translate into the following recommendations: A UV Index of 3 to 5 symbolizes a moderate health risk from unsafe exposure to UV radiation for ordinary individuals. UV index January, February, November and December, with an average maximum UV index of 4, are months with the lowest UV index in Corona. SunshineThe month with the least sunshine in Corona is December, with an average of 6.7h of sunshine. On the last day of December, in Corona, sunrise is at 6:55 am and sunset at 4:51 pm PST. On the first day of the month, sunrise is at 6:37 am and sunset at 4:41 pm. DaylightDecember has the shortest days of the year in Corona, with an average of 9h and 56min of daylight. RainfallThe month with the most rainfall in Corona is December, when the rain falls for 6.5 days and typically aggregates up to 1.89" (48mm) of precipitation. HumidityIn Corona, the average relative humidity in December is 53%. TemperatureWith an average high-temperature of 63.5☏ (17.5☌) and an average low-temperature of 46.9☏ (8.3☌), December is the coldest month. The first month of the winter, December, is also an enjoyable month in Corona, California, with an average temperature ranging between min 46.9☏ (8.3☌) and max 63.5☏ (17.5☌).
