Natural Environment of Poland: Climate

Vocabulary flashcards covering the natural climate of Poland, including pressure systems, air masses, seasonal classifications, mountain climate phenomena, and urban climate change dynamics.

Temperate warm transitional climate

The classification of the Polish climate according to Okołowicz.

Hemiboreal climate (type Dfb)

A warm summer humid continental climate classification for Poland according to Koeppen.

Azores High

One of the three main pressure systems affecting the Polish climate, alongside the Icelandic Low and Siberian High.

Icelandic Low

A major pressure system influencing weather in Poland, typically associated with the advection of maritime Polar air masses.

Siberian High

A main pressure system that influences the Polish climate, particularly during the winter period.

maritime Polar (mP) air mass

The most frequent air mass over Poland, occurring approximately $46\%$ of the year.

continental Polar (cP) air mass

An air mass with a frequency of $38\%$ over Poland, originating from the big land mass of the Eurasian continent.

Pre-Spring (thermal season)

A thermal season defined by Romer where the average temperature range is $0.0\,^{\circ}\text{C} < t \leq 5.0\,^{\circ}\text{C}$.

Spring (thermal season)

A thermal season defined by Romer where the average temperature range is $5.0\,^{\circ}\text{C} < t \leq 15.0\,^{\circ}\text{C}$.

Summer (thermal season)

A thermal season defined by Romer where the average temperature is $t \geq 15.0\,^{\circ}\text{C}$.

Winter (thermal season)

A thermal season defined by Romer where the average temperature is $t \leq 0.0\,^{\circ}\text{C}$.

Trajectory Vb

A low-pressure system path from the Great Hungarian Plain responsible for deep low-pressure systems, heavy rainfalls, and floods in Poland.

Halny

A specific type of foehn wind occurring in the Tatra mountains, characterized by being a warm, dry mountain wind.

Thermal inversion

A common climate property in Polish mountain valleys and basins where temperature increases with altitude.

Lee waves

Atmospheric waves in the Tatra mountains that influence cloud formation and other weather aspects.

Brocken spectre

An optical phenomenon observed in the Polish mountains involving the magnified shadow of an observer cast upon clouds.

Urban Heat Island

A thermal anomaly in urbanized areas like Warsaw characterized by higher temperatures compared to surrounding natural areas due to anthropogenic heat and infrastructure.

Exposure

In the context of climate assessment, it is the evaluation of present and future presence of negative conditions caused by climate change.

Vulnerability

In the context of climate assessment, it is how susceptible a city, its infrastructure, and inhabitants are to the negative conditions of climate change.

Mitigation

Actions taken to reduce predicted changes in the urban climate, such as increasing green areas or using zero-emission vehicles.

Adaptation

Adjusting the economy and society to unavoidable climate changes, such as upgrading infrastructure or monitoring hotspots.

Convective Available Potential Energy (CAPE)

A measure used to assess the buoyancy of air masses and the risk of severe weather events like thunderstorms.
