The most precipitation in one month was in February 1998.

This model relates the distribution of major ecosystems ( life zones ) to the climate variables of biotemperature, mean precipitation, and the ratio of potential evapotranspiration to precipitation (PET ratio).

In Puerto Rico, it grows in areas receiving from 900 to 2500 mm of precipitation.

Quantum dots were discovered by Alexey Ekimov at first in 1981 in a glass matrix and then in colloidal solutions by Louis E. Brus in 1985.

Precipitation, however, has been increasing in the last few decades, with accumulated rain reaching per year.

Because of the size exclusion, the colloidal particles are unable to pass through the pores of an ultrafiltration membrane with a size smaller than their own dimension.

Each climate has its own sub climates, reflecting the amount of precipitation and the length of the rainy season.

Dry lightning is used in Australia, Canada and the United States for lightning that occurs with no precipitation at the surface.

Precipitation is moderate to heavy in most parts of the country the heavier rainfall occurs in the low lying hot zone.

The environmental affects may include diurnal temperature cycling, vibration, shock, humidity, solar radiation, precipitation, sand dust, salt spray and electromagnetic radiation.

Average precipitation is heavy, a result of the convergence of the prevailing airflow from the Mediterranean Sea and the continental air mass.

There, an average of 180 days per year have precipitation, forty four days have fog, and only seventy two days are sunny.

This precipitation has helped provide the abundant water for Latvia's many rivers and lakes, but it has created many problems as well.

The south western part of the country receives more precipitation, between , and some mountain areas in the north are estimated to receive up to .

On average, Anchorage receives of precipitation a year, with around of snow, although there are areas in the south central which receive far more snow.

Flocks was the first to experiment with antigens in the prostate and 10 years later Albin reported the presence of precipitation antigens in the prostate.

It is characterized by developed landscapes with relatively high slopes which, in addition to the unbalanced distribution of precipitation, lead to an unbalanced off flow.

Authors review the previous pathogenic theories, discuss the link between concentric sclerosis and Liesegang's periodic precipitation phenomenon and propose a new mechanism based on self organization.

Further, these mountains catch the precipitation of the monsoon winds of the Indian Ocean, resulting in a rainy season that lasts from June until mid September.

Global warming could lead to an increase in freshwater in the northern oceans, by melting glaciers in Greenland and by increasing precipitation, especially through Siberian rivers.

Precipitation in Ukraine is disproportionately distributed, with the most falling in the west and the north, and much less falling in the east and the southeast.

Many parts of Mexico, particularly the north, have a dry climate with sporadic rainfall while parts of the tropical lowlands in the south average more than of annual precipitation.

Extensive areas of the Caribbean interior are permanently flooded, more because of poor drainage than because of the moderately heavy precipitation during the rainy season from May through October.

There is evidence that the frequency and intensity of extreme precipitation events will increase over many areas worldwide, notably over many northern hemisphere mid to high latitude land areas.

Observing systems. Understanding atmospheric change requires an integrated system for collecting data on a wide array of parameters, including greenhouse gases, ozone, solar radiation, precipitation chemistry, aerosols, reactive gases and meteorology.

At this time a dramatic shift in climate occurred, causing a significant drop in precipitation in the Titicaca Basin, believed by archaeologists to have been on the scale of a major drought.

These health hazards range from deaths related to extreme high temperatures and natural disasters to a change in patterns of diseases that are sensitive to temperature and precipitation, such as malaria and dengue.

The least precipitation is recorded in the outer islands (Vis, Lastovo, Biševo, Svetac) and in the eastern parts of Slavonia, however in the latter case, it is mostly occurring during the growing season.

We are now learning how those environmental impacts are aggravated by atmospheric pollution, acid precipitation and atmospheric concentration of greenhouse gases and why global climate change may pose the most serious threat of them all.

What we don't know is the exact, precise, immediate impact of these changes on natural climate patterns winds, ocean currents, precipitation rates, cloud formation, things that bear on the health and well being of billions of people.

The various rivers and streams in the area were engorged by increased precipitation and with melt water from mountain glaciers on the Henry Mountains to the east and the Aquarius Plateau to the west of the park.

But can science and technology really solve problems that are not caused by China alone? More and more scientists are beginning to suspect that global warming has caused the radically changed patterns of precipitation now seen across China.

Authorities in Heilongjiang denied the Russian officials' claims, telling the Global Times today that farmers in the province had not yet begun to harvest crops or burn straw and won't begin do so until early November because of recent precipitation.

Hydrology In hydrology, the drainage basin is a logical unit of focus for studying the movement of water within the hydrological cycle, because the majority of water that discharges from the basin outlet originated as precipitation falling on the basin.

In addition to the maritime and continental climates that predominate over most of the country, the Alpine regions in the extreme south and, to a lesser degree, some areas of the Central German Uplands have a mountain climate, with lower temperatures and greater precipitation.

Weather and climate in the coastal area are dominated by the cold, north flowing Benguela current of the Atlantic Ocean which accounts for very low precipitation (50 mm per year or less), frequent dense fog, and overall lower temperatures than in the rest of the country.
