Abstract

Deschamps and Mottez (hereafter DM) argue that the Gauss-Matuyama terrestrial magnetic field reversal may have left a vanishing main dipole moment to the field for a time of order 10,000 years. They say this may have allowed an enhanced cosmic ray flux, boosting the effect we proposed in Melott and Thomas (2019). We point out that the bulk of the cosmic ray flux from a nearby supernova should be too energetic, up to a million times more energetic than the limits of deflection by the terrestrial magnetic field. In fact, only those highly energetic ones will directly reach the troposphere, relevant for cloud-to-ground lightning. From Cosmic Explosions to Terrestrial Fires?: A Discussion. F. Deschamps and F.

从宇宙爆炸到陆地火灾？答覆

Deschamps和Mottez（以下简称DM）认为，高斯-马图亚马地面磁场反转可能在大约10000年的时间里给磁场留下了消失的主偶极矩。他们说，这可能增强了宇宙射线通量，增强了我们在Melott和Thomas（2019）中提出的效果。我们指出，来自附近超新星的大部分宇宙射线通量应该能量太大，比地球磁场偏转极限的能量高出一百万倍。事实上，只有那些高能的才会直接到达对流层，这与云对地闪电有关。从宇宙爆炸到陆地火灾？：讨论。F.德尚和F.莫特兹。J.Geology 128，在线预刊。（2020）从宇宙爆炸到陆地火灾？：A.L.Melott和B.C.Thomas的回复。J.Geology 128，在线预刊。（2020）从宇宙爆炸到地面火灾？（A.L.Melott和B.C.Thomas）《地质学杂志》，127475-481 10.1086/703118（2019）[arXiv:1903.01501]

期刊介绍： One of the oldest journals in geology, The Journal of Geology has since 1893 promoted the systematic philosophical and fundamental study of geology. The Journal publishes original research across a broad range of subfields in geology, including geophysics, geochemistry, sedimentology, geomorphology, petrology, plate tectonics, volcanology, structural geology, mineralogy, and planetary sciences. Many of its articles have wide appeal for geologists, present research of topical relevance, and offer new geological insights through the application of innovative approaches and methods.
