Italy – December 28th, 2012

Snow rests on the crests of the Alps, in northern Italy, while the peaks of the Apennines, running down the center of the country, are mostly snow-free. Lake Garda can be seen at the foot of the Alps, the southern part of its basin reaching towards the Po Valley, which flanks the River Po and is nestled between the Alps and the northern segment of the Apennines.

The Alps, covered in snow, arch across the upper part of this image, marking the border between Italy (right) and Switzerland (above, left) and France (below, left). A plume of smoke from a fire near Lake Geneva blows southward and then curves to the west, trailing out over the Mediterranean Sea.

Italy - December 26th, 2011

This wide-swath ASAR image shows the contours of the Alps, in northern Italy, as well as parts of Switzerland and Austria. Visible in the Po Valley south of the mountains is the city of Milan, appearing as a large, circular, white area.

Also visible near the foot of the mountains are several lakes: Lake Garda, in Italy, near the center of the image, and Lake Constance, shared by Germany, Switzerland and Austria, in the upper left corner. The Rhine River flows into Lake Constance from the south following the Austro-Swiss border.

Lakes Between Rome and Apennine Mountains, Italy

Italy - December 31st, 2011

This image focuses on central Italy, from the Adriatic (above) to the Tyrrhenian (below) Seas. The Adriatic Coast is lined by sediments, while the Tyrrhenian coastline is mostly sediment free. The ridges of the Apennine Mountains can be seen running down the middle of the Italian peninsula, part of which are capped by snow.

The city of Rome can be seen in the full image, appearing as a grey area near the coast in the bottom half of the image. Visible to the west and northwest of the city are three large lakes: Lake Bracciano (dark blue, closest to Rome), Lake Bolsena (dark blue, northwest of the former) and Lake Trasimeno (light blue, located near the center of the width of the peninsula).

Wave Clouds Over Apennine Mountains, Italy

Italy - December 26th, 2011

Sediments line the Adriatic coast of Italy (right) while the western coast is mostly clear. Several rounded crater lakes are visible near the west coast in the central part of the country, the largest of which is Lake Bolsena, formed starting 370,000 years ago following the collapse of a caldera of the Vulsini volcanic complex into a deep aquifer.

Visible northeast of the lake are wave clouds, formed by atmospheric internal waves that are created as stable air flows over a raised land feature such as a mountain range, and can form either directly above or in the lee of the feature. Here, the wave clouds have formed over the Apennine Mountains.
