President-elect Joseph R. Biden Jr. plans to name several top national security picks on Tuesday, his transition office said, including the first Latino to lead the Department of Homeland Security, the first woman to head the intelligence community and a former secretary of state, John Kerry, to be his climate czar.

At an event in Wilmington, Del., Mr. Biden will announce plans to nominate Alejandro Mayorkas to be his secretary of the Department of Homeland Security, his transition office said, and Avril Haines to be his director of national intelligence. He intends to name Mr. Kerry as a special presidential envoy on climate. The transition office also confirmed reports on Sunday night that Mr. Biden will nominate Antony J. Blinken to be secretary of state and Jake Sullivan as national security adviser.
