The minimum temperature at Jingtao automated weather station in the town of Amur, Mohe City in Heilongjiang Province, China fell to -53.0°C (-63.4°F) on January 22, 2023, marking the lowest temperate in the province and the lowest ever observed by the Chinese meteorological system.
The Volcanology and Geological Disaster Mitigation Center (PVMBG) reported that beginning in July 2022, the seismic network at Ijen volcano in East Java, Indonesia began detecting increasing numbers of shallow volcanic earthquakes and earthquake signals characteristic of emissions, indicating increasing pressure at shallow depths within the hydrothermal system.
A powerful low pressure system, named Storm Gerard by Météo France, brought heavy rainfall, strong winds, and thunderstorms to northern and western France on Sunday, January 15, and Monday, January 16, 2023, resulting in significant weather-related incidents and causing casualties and damage. This is the 22nd named storm of the 2022/23 European windstorm season, including two ex-hurricanes (Danielle and Martin).
Residents in parts of central Latvia were urged to evacuate their homes on January 15, 2023, due to the worst flooding the state has seen since 1981.
New research from the Wilcox Solar Observatory (WSO) has found evidence for the correspondence of the “Extended Solar Cycle” (ESC) to the Sun’s Hale magnetic cycle. The research emphasizes the intrinsic power of synoptic observations, particularly at a time when it is becoming increasingly difficult to sustain such efforts.
The Hunga Tonga-Hunga Ha’apai volcano eruption on January 15, 2022, has set a new record for the greatest concentration of lightning ever detected. According to data from Vaisala’s Global Lightning Dataset GLD360, nearly 400 000 lightning events were detected within just six hours of the eruption, making it a truly exceptional phenomenon.
Solar activity increased over the past 4 days, with numerous C- and M-class solar flares and one X-class flare. With now geoeffective AR 3182, the source of the X1.2 solar flare on January 6, developing unstable ‘beta-gamma-delta’ magnetic configuration, the chances for more X-class solar flares have increased to 30%.
Four Corners, Florida has been crowned the new lightning capital of the United States, with a record-breaking 474 lightning events per square kilometer. The title was previously held by Flatonia, Texas, situated halfway between Houston and San Antonio.
Monitoring stations installed in the vicinity of the massive Ollagüe stratovolcano in the Andes, on the border between Bolivia and Chile, detected increased seismicity under the volcano on January 2, 2023.
Geomagnetic storms reaching G1 – Minor levels are likely on January 4 and 5, 2023 due to combined effects of a coronal mass ejection (CME) that left the Sun on December 30 and coronal hole high speed stream (CH HSS) effects. Solar activity is expected to be at low levels, with a chance for M-class flares through January 28.
