Abstract: The pulsed electromagnetic radiation from a vertical magnetic dipole above a conducting Earth is investigated theoretically. The modified Cagniard method is used to derive closed form ...

Eerie bird sounds are coming from space – and astronomers finally understand why - Energy waves behind the chirping sound ...

Electromagnetic chorus waves once thought to only exist close to the Earth have been found at a distance of 165,000 ...

During solar minimum, the sun's magnetic field is close to a dipole, with one north pole and one south pole, similar to Earth's magnetic field. But as we shift toward solar maximum, "the sun's ...

研究组展示了大平原南部陆地上的局部负地表长波云反馈，受到光谱分辨下行长波辐射的直接长期观测的约束。这种在大平原南部地区的负云反馈导致下行长波辐射每10年减少1.77±1.15Wm?2，这表明云的变化可能部分调节了陆地上温室气体浓度增加和大气温度升高的变暖效应。具体而言，该结果源于一种最佳的光谱指纹识别方法，旨在通过利用光谱分辨辐射长期记录中的独特光谱特征，将表面长波云反馈与其他地表强迫和反馈分离开 ...

Molecules haven't been used in quantum computing, even though they have the potential to make the ultra-high-speed ...

Scientists have released a new model tracking the position of the magnetic north pole, revealing that the pole is now closer to Siberia than it was five years ago and is continuing to drift toward ...
