Alexander Ivanovich Voeikov (Александр Иванович Воейков, 20 May 1842 – 9 February 1916) was a Russian meteorologist and climatologist who was involved in establishing meteorological stations across Russia.
He described a Siberian high pressure area extending into South West Europe which is known as the Voeikov Axis.
Voeikov was born in Moscow to Ivan Fedorovich but orphaned at the age of five, he was raised by his maternal uncle D. D. Mervago.
Among Voeykov's contributions were the use of budgets of evaporation, inflow and outflow of rivers to examine trends.
[1][2][3][4][5] The so-called Voeikov Axis of high pressure from Siberia to southwestern Europe is named after him.
