The Gulf and South Atlantic states have a humid subtropical climate with mostly mild winters and hot, humid summers. Most of the Florida peninsula including Tampa and Jacksonville, along with other coastal cities like Houston, New Orleans, Savannah, Charleston and Wilmington all have average summer highs from near 90 to the lower 90s F, and lows generally from 70 to 75 °F (21 to 24 °C ...
The glaciations that occurred during the glacial period covered many areas of the Northern Hemisphere. Northern hemisphere glaciation during the last ice ages. The setup of 3 to 4 kilometer thick ice sheets caused a sea level lowering of about 120 m. The Arctic is a region around the North Pole (90° latitude). Its climate is characterized by ...
Continental climates occur mostly in the Northern Hemisphere due to the large landmasses found there. Most of northeastern China, eastern and southeastern Europe, much of Russia south of the Arctic Circle, central and southeastern Canada, and the central and northeastern United States have this type of climate.

The maps are derived from U.S. climate normals provided by the National Centers for Environment Information (NCEI): The dataset consists of the latest 30-year average of weather data, including ...
Today, the most commonly used climate map is the Köppen climate classification, developed by Russian climatologist of German descent and amateur botanist Wladimir Köppen (1846–1940), which divides the world into five major climate regions, based on average annual precipitation, average monthly precipitation, and average monthly temperature.
A Köppen–Geiger climate map showing temperate climates for 1991–2020 The different geographical zones of the world. The temperate zones, in the sense of geographical regions defined by latitude, span from either north or south of the subtropics (north or south of the orange dotted lines, at 35 degrees north or south) to the polar circles.
Within North America, moisture within this climate regime is supplied by the Great Lakes, Gulf of Mexico and adjacent western subtropical Atlantic. [8] Precipitation is relatively well distributed year-round in many areas with this climate (f), while others may see a marked reduction in wintry precipitation, [6] which increases the chances of a wintertime drought (w).

280 if 70% or more of the total precipitation is in the high-sun half of the year (April through September in the Northern Hemisphere, or October through March in the Southern), or; 140 if 30%–70% of the total precipitation is received during the applicable period, or; 0 if less than 30% of the total precipitation is so received.
